The comparator is a high-gain amplifier that is used to amplify a small differential signal at its input, and drive the output to one of two output states. Figure 1 shows the basic comparator circuit, ...

Testing a set of analog comparators for hysteresis can be a time-consuming process. You have to accurately find the threshold voltages for numerous devices across variations in fabrication process, ...

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 ...

Comparators are great at turning little signals into large digital outputs. In the example described here, a friend wanted to detect the presence of a small 60-Hz ac signal centered on 2.5 V dc. When ...

Toshiba Electronic Devices & Storage Corporation ("Toshiba") has launched a CMOS dual comparator, "TC75W71FU." It features a high-speed response and a full input/output range (Rail to Rail), suiting ...
