A high-speed comparator for use in an ADC
B. J. McCarroll, C.G. Sodini, H.-S. Lee · 1987
The conversion time for high-speed analog-to-digital converters is limited by the rate at which the internal comparator(s) can amplify small voltages 1 into logic levels. Several comparators have been designed with response times of less than 10 ns [1,2]. However, these circuits are usually fabricated with bipolar transistors.
