A 300°C dynamic-feedback instrumentation amplifier
Copyright policy )A 300°C dynamic-feedback instrumentation amplifier
A high-temperature instrumentation amplifier that uses dynamic feedback is presented. It realizes dynamic feedback by means of a rotating chain of resistors to compensate for resistor mismatches. An 11x dynamic-feedback instrumentation amplifier has been integrated in a standard junction-isolated 1.6-μm CMOS process and realizes an average gain error below 25 ppm up to 250°C without calibration or trimming. Leakage currents cause additional gain errors at higher temperatures. Nevertheless, even at 300°C, this average gain error is still less than 500 ppm.
