| Abstract | The overall performance of two-step flash A/D converters hinges on the second-stage fine comparator. This paper descibes the design of a60 MHz fully differential comparator, intended for use in a 12-bit two-step flash converter. The comparator consists of four pre-amplifier stages followed by a regenerative latch. It uses a combination of output offset cancelation and input offset cancelation to acheive150 mV resolution. The comparator is designed to operate from a 2.5V supply, has an active area of 522 μm, and consumes 247 μW of power. |
