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 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 ...

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 ...

Analysis of this circuit is simplified by the fact that the output has only two states: V out low (Vol) or V out hi (Voh). In this circuit, Voh is equal to the positive supply voltage and Vol is ...

This resource was designed to be used in conjunction with Cambridge IGCE Physics unit 'direct sensing'. The content relates to voltage gain of an opamp, comparator, inverting amplifier, and ...

Theory for GCSE electronics & electronic products focusing on comparators and inverting amplifiers. A more detailed discussion on op amps is available but this is not needed at GCSE A resource ...
