Voltage comparators began appearing in single-chip microcontrollers (MCUs) in the late 1990s. At the time, the change was viewed as a simple cost reduction. Comparators required less silicon, while ...

In VLSI applications, area, delay and power are the important factors which must be taken into account in the design of a fast adder. The paper attempts to examine the features of certain adder ...

Comparators are one of the basic building blocks of analog and mixed-signal designs, providing one small but critical function, as their name indicates. Their role is often to be a “simple” safety ...
