Abstract :
A pipelined ADC based upon a new error correction algorithm is presented. With a 10% mismatch in capacitor sizes, the proposed ADC achieves a simulated DNL (differential non-linearity) of 9 bits can be-realized. Spice level simulations based upon extracted layout of the chip designed in a 1.2 μm CMOS process show that 3.3 MSamples/s can be resolved at 20 mW per bit
