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, ...

A common feature in most of the electronic devices we use – cell phones, PDAs, notebooks, handheld media players, game systems, etc. – is the provision for connecting external accessories. Such ...

A comparator is a great circuit because it provides a near ideal transition between the analog and digital domains. The comparator looks at two linear input signals and gives a digital output that’s ...

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 ...

1. A conventional circuit uses a diode after the comparator to rectify the output onto C3. The circuit uses an LT1716 comparator. R2/R3 set up a 10-mV threshold to keep the output normally high, and ...
