Because digital systems often have only a single-polarity power supply, a common problem becomes translating an opposite-polarity pulse train into a positive-or negative-pulse output. Here are some ...

A comparator is an electronic component that outputs different voltage results at the output by comparing the magnitude of the current or voltage at the two inputs. This article describes the ...

In this section we will discuss some fundamental digital building blocks for power management. We will quickly review the main properties of the elementary components, the logic gates, so that we can ...
