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, ...

Although humble in concept, today’s voltage comparators perform a simple basic task: comparing two voltages to determine which is larger. To accomplish this task, they accept two analog signals and ...

A rubidium standard, or rubidium atomic clock, is a high accuracy frequency and time standard, usually accurate to within a few parts in 10 11. This is still several orders of magnitude less than some ...

At times, designers face a limited amount of wire and/or a limited cost to communicate with a remote device such as a sensor. Many devices allow communication over an ac or dc power line employing an ...
