Abstract :
A switched-capacitor algorithmic A/D convertor is described, in which the amplifier offset compensation is inherent to the circuit structure and the effect of clock-feedthrough is as low as 0.5 mV. Preliminary experimental results, obtained on circuits fabricated using a low-voltage CMOS technology, indicate 8-bit resolution for 15 kHz sampling frequency, with only 350 ¿W power consumption.
