Abstract

Successive approximation register (SAR) analog-to-digital converters (ADCs) generally use one or more comparators to convert an analog signal to a digital signal. These comparators, however, can consume a great deal of power, so it is desirable to have a comparator configuration that consumes less power. Here, a multi-bandwidth comparator is provided, which can be switched between different coarse resolution and fine resolution. By using this single multi-bandwidth comparator, lower power consumption with a small amount of area can be achieved.
