A high speed, low voltage CMOS offset comparator
A high speed, low voltage offset comparator is presented. No common mode tracking circuit is used and the offset is added without compromising the high input impedance nature of the circuit. The circuit operates at 480 Mbps with 3.0-3.6 V and 1.6-2.0 V supplies and -40 to 125 degreesC temperature range on a typical 0.5 mum technology.
