The Design of a Comparator [The Analog Mind]
Behzad Razavi
Abstract
Nyquist-rate and oversampling analog- to-digital converters (ADCs) incorporate comparators to perform quantization and possibly sampling. Comparators thus have a significant impact on the speed and precision of ADCs. This article presents the step-by-step design of a comparator and the discovery of its various trade-offs.
