Schemes of two-half-period rectifiers on op amps with switching inputs in accordance with the polarity of the input voltage are given. The switching of inputs is performed by a control signal taken ...

If you are designing a system that measures a number of analog voltages, but not all at the same time, you can reduce downstream circuitry by multiplexing the measurements into a single output signal, ...

Conventional rectifiers employing diodes can’t be used with low-amplitude signals. This Idea for Design describes a circuit using Analog Devices' AD844 op amps to create a mixed-mode precision ...

Whenever you need an amplifier or have a related linear-circuit design problem, most of you will turn to an op amp as a solution. Op amps are a good choice because of their universal versatility to ...
