Abstract :
A new structure of switched-capacitor AID converter is described, in which the effects of amplifier offsets and charge injection are compensated. Compared to a 1st ordre structure, the use of a second order scheme allows a substantial reduction in the conversion time. Experimental results, obtained on circuits fabricated using a CMOS technology, indicate that 15 bit accuracy is easily achievable.
