Chopper-Stabilized Instrumentation Amplifier with Automatic Frequency Tuning Loop

Chopper-Stabilized Instrumentation Amplifier with Automatic Frequency Tuning Loop

A variable-gain chopper-stabilized instrumentation amplifier (chopper IA), which employs a low pass filter (LPF) to attenuate the up-converted noise at the chopping frequency, is presented. The circuit is designed and fabricated with Taiwan Semiconductor Manufacturing Company (TSMC) (Hsinchu, Taiwan...
