Abstract: Comparators play a pivotal role in design of analog and mixed signal circuits. Comparators employ regenerative feedback both in input pre-amplifier stage and output stage. The designed comparator resolves 5mV with resolution of 8 bits and dissipates 11mW of power using 1.2V supply in 130nm CMOS technology while operating at clock frequency of 1.25 GHz.
Keywords: Dynamic Comparator, Offset Voltage, Kickback Noise.
Scope of the Article: Foundations Dynamics.
