Abstract :
Switched-capacitor integrator circuits are described, in which the effects of amplifier offset and clock feedthrough are both compensated for using a sampled-data feedback path. Preliminary experimental results, obtained on circuits fabricated using a low-voltage CMOS technology, indicate 40¿60 dB reduction in these effects.
