ABSTRACT:
A switched-capacitor integrator with chopper stabilization performed at the sampling rate virtually eliminates the flicker noise and any low frequency interference generated by the amplifier. The integrator samples the input and then passes the sampled input to the feedback capacitor during each chopping phase of the amplifier to thereby provide a double-sampled integrator. The output of the integrator is sampled at the end of each cycle of the chopping signal.
