Comparator

🖼️ ➺

In electronics, a comparator is a device that compares two voltages or currents and outputs a digital signal indicating which is larger. It has two analog input terminals $V_{+}$ and $V_{-}$ and one binary digital output $V_{\text{o}}$. The output is ideally

• ✤ $V_{\text{o}}=\{\begin{array}{ll}1,& \text{if }{V}_{+}>V_{-},\\ 0,& \text{if }{V}_{+}<V_{-}.\end{array}$

A comparator consists of a specialized high- gain differential amplifier. They are commonly used in devices that measure and digitize analog signals, such as analog-to-digital converters (ADCs), as well as relaxation oscillators.
