High-Speed Low-Power Flash ADC Architecture Using Switched-Capacitor Positive Feedback Comparator and Parallel Single-Gate Encoder
Abstract In this paper, two essential components of the Flash ADC are designed and integrated within a new Flash ADC architecture. The power consumption is reduced by realizing a switched-capacitor positive feedback (SCPF) comparators structure as a replacement for conventional comparators structure...

| 520 | |a Abstract In this paper, two essential components of the Flash ADC are designed and integrated within a new Flash ADC architecture. The power consumption is reduced by realizing a switched-capacitor positive feedback (SCPF) comparators structure as a replacement for conventional comparators structure. The SCPF comparator is tailored to a single-ended input/single-ended output configuration that operates in two steps: offset-cancelation function followed by comparison decision. Furthermore, the encoding stage is implemented using N parallel independent components of one single AND gate each, where N is the number of quantized regions. This structure provides fast encoding with minimal encoding activities. The design architecture exploits two stages, which are separated by latches. The first stage allocates the analog input to a quantized region, while the second stage converts the level of the quantized region into its corresponding binary code. This separation is considered the key success for incorporating the SCPF comparators structure into our Flash ADC architecture. HSPICE simulations of the proposed design use 35 nm Synopsys FinFet technology and 1-V power supply. The simulation results show that our 5-bit Flash ADC can function at a sampling frequency of up to 1 GHz, with an input signal of 500 MHz at Nyquist rate, where the amplitude input signal is ranging from 0.2 to 0.8 V with an overall maximum power consumption of 3 mW. | ||

The power consumption is reduced by realizing a switched-capacitor positive feedback (SCPF) comparators structure as a replacement for conventional comparators structure. The SCPF comparator is tailored to a single-ended input/single-ended output configuration that operates in two steps: offset-cancelation function followed by comparison decision. Furthermore, the encoding stage is implemented using N parallel independent components of one single AND gate each, where N is the number of quantized regions. This structure provides fast encoding with minimal encoding activities. The design architecture exploits two stages, which are separated by latches. The first stage allocates the analog input to a quantized region, while the second stage converts the level of the quantized region into its corresponding binary code. This separation is considered the key success for incorporating the SCPF comparators structure into our Flash ADC architecture. HSPICE simulations of the proposed design use 35 nm Synopsys FinFet technology and 1-V power supply. The simulation results show that our 5-bit Flash ADC can function at a sampling frequency of up to 1 GHz, with an input signal of 500 MHz at Nyquist rate, where the amplitude input signal is ranging from 0.2 to 0.8 V with an overall maximum power consumption of 3 mW.

The power consumption is reduced by realizing a switched-capacitor positive feedback (SCPF) comparators structure as a replacement for conventional comparators structure. The SCPF comparator is tailored to a single-ended input/single-ended output configuration that operates in two steps: offset-cancelation function followed by comparison decision. Furthermore, the encoding stage is implemented using N parallel independent components of one single AND gate each, where N is the number of quantized regions. This structure provides fast encoding with minimal encoding activities. The design architecture exploits two stages, which are separated by latches. The first stage allocates the analog input to a quantized region, while the second stage converts the level of the quantized region into its corresponding binary code. This separation is considered the key success for incorporating the SCPF comparators structure into our Flash ADC architecture. HSPICE simulations of the proposed design use 35 nm Synopsys FinFet technology and 1-V power supply. The simulation results show that our 5-bit Flash ADC can function at a sampling frequency of up to 1 GHz, with an input signal of 500 MHz at Nyquist rate, where the amplitude input signal is ranging from 0.2 to 0.8 V with an overall maximum power consumption of 3 mW.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Flash ADCs</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Digital signal processing</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">High-speed low-power</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">FinFet technology</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Switched-capacitor positive feedback comparator</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Thermometer encoder</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Shatnawi, Ali</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Circuits, systems and signal processing</subfield><subfield code="d">Boston, Mass. : Birkhäuser, 1982</subfield><subfield code="g">37(2017), 6 vom: 25.

High-Speed Low-Power Flash ADC Architecture Using Switched-Capacitor Positive Feedback Comparator and Parallel Single-Gate Encoder |
| abstract |
Abstract In this paper, two essential components of the Flash ADC are designed and integrated within a new Flash ADC architecture. The power consumption is reduced by realizing a switched-capacitor positive feedback (SCPF) comparators structure as a replacement for conventional comparators structure. The SCPF comparator is tailored to a single-ended input/single-ended output configuration that operates in two steps: offset-cancelation function followed by comparison decision. Furthermore, the encoding stage is implemented using N parallel independent components of one single AND gate each, where N is the number of quantized regions. This structure provides fast encoding with minimal encoding activities. The design architecture exploits two stages, which are separated by latches. The first stage allocates the analog input to a quantized region, while the second stage converts the level of the quantized region into its corresponding binary code. This separation is considered the key success for incorporating the SCPF comparators structure into our Flash ADC architecture. HSPICE simulations of the proposed design use 35 nm Synopsys FinFet technology and 1-V power supply. The simulation results show that our 5-bit Flash ADC can function at a sampling frequency of up to 1 GHz, with an input signal of 500 MHz at Nyquist rate, where the amplitude input signal is ranging from 0.2 to 0.8 V with an overall maximum power consumption of 3 mW. © Springer Science+Business Media, LLC 2017 |
