A low power 10-bit 250-k sample per second (KSPS) cyclic analog to digital converter (ADC) is presented. The ADC's offset errors are successfully cancelled out through the proper choice of a capacitor switching s...
Based on a physical understanding of nonlinearity and mismatch, a novel offset-cancellation technique for low voltage CMOS differential amplifiers is proposed. The technique transfers the offset voltage from the outpu...
