Design of a high temperature resistant instrument amplifier using high temperature gain self-calibration technology

In order to solve the problems of offset voltage, noise increase and closed-loop gain accuracy degradation caused by high temperature, a low-noise instrument amplifier with high-temperature gain self-calibration technology (HGST) is designed under SMIC 0.18 μ m CMOS p...

The op amp adopts a two-stage amplification, three-stage chopper modulation structure, with an operating voltage range of 1.8–2.5 V, a quiescent current consumption of 100 μ A, and a chopper clock frequency of 250 kHz. The simulation results show that the equivalent input noise spectral density at 1 Hz is 57.8 nV/ Hz , the thermal noise is 34.5 nV/ Hz , and the DC offset voltage range is 127.15 μ V. In the case of a 100 °C environment with an ideal output peak value of 127.6 mV, the high-temperature gain self-calibration technology proposed in this paper can increase the peak output voltage of 120.2 mV to 126.0 mV, reduce the voltage error by 5.8 mV, and optimize the temperature coefficient from 535.43 ppm/°C to 86.55 ppm/°C. The simulation results show that the proposed high-temperature gain self-calibration technology can solve the problems of offset voltage, noise increase and closed-loop gain accuracy decrease in high-temperature environment. This means that the instrument amplifier can be used as one of the important components of the geophone in high-temperature environments such as deep well detection.

The simulation results show that the equivalent input noise spectral density at 1 Hz is 57.8 nV/ Hz , the thermal noise is 34.5 nV/ Hz , and the DC offset voltage range is 127.15 μ V. In the case of a 100 °C environment with an ideal output peak value of 127.6 mV, the high-temperature gain self-calibration technology proposed in this paper can increase the peak output voltage of 120.2 mV to 126.0 mV, reduce the voltage error by 5.8 mV, and optimize the temperature coefficient from 535.43 ppm/°C to 86.55 ppm/°C. The simulation results show that the proposed high-temperature gain self-calibration technology can solve the problems of offset voltage, noise increase and closed-loop gain accuracy decrease in high-temperature environment. This means that the instrument amplifier can be used as one of the important components of the geophone in high-temperature environments such as deep well detection.

The op amp adopts a two-stage amplification, three-stage chopper modulation structure, with an operating voltage range of 1.8–2.5 V, a quiescent current consumption of 100 μ A, and a chopper clock frequency of 250 kHz. The simulation results show that the equivalent input noise spectral density at 1 Hz is 57.8 nV/ Hz , the thermal noise is 34.5 nV/ Hz , and the DC offset voltage range is 127.15 μ V. In the case of a 100 °C environment with an ideal output peak value of 127.6 mV, the high-temperature gain self-calibration technology proposed in this paper can increase the peak output voltage of 120.2 mV to 126.0 mV, reduce the voltage error by 5.8 mV, and optimize the temperature coefficient from 535.43 ppm/°C to 86.55 ppm/°C.

abstract	In order to solve the problems of offset voltage, noise increase and closed-loop gain accuracy degradation caused by high temperature, a low-noise instrument amplifier with high-temperature gain self-calibration technology (HGST) is designed under SMIC 0.18 μ m CMOS process, and a low-noise operational amplifier with low offset voltage and low noise is composed of dual op amps. The op amp adopts a two-stage amplification, three-stage chopper modulation structure, with an operating voltage range of 1.8–2.5 V, a quiescent current consumption of 100 μ A, and a chopper clock frequency of 250 kHz. The simulation results show that the equivalent input noise spectral density at 1 Hz is 57.8 nV/ Hz , the thermal noise is 34.5 nV/ Hz , and the DC offset voltage range is 127.15 μ V. In the case of a 100 °C environment with an ideal output peak value of 127.6 mV, the high-temperature gain self-calibration technology proposed in this paper can increase the peak output voltage of 120.2 mV to 126.0 mV, reduce the voltage error by 5.8 mV, and optimize the temperature coefficient from 535.43 ppm/°C to 86.55 ppm/°C. The simulation results show that the proposed high-temperature gain self-calibration technology can solve the problems of offset voltage, noise increase and closed-loop gain accuracy decrease in high-temperature environment. This means that the instrument amplifier can be used as one of the important components of the geophone in high-temperature environments such as deep well detection.
