In rectifier circuits, the voltage drop that occurs with an ordinary semiconductor rectifier can be eliminated to give precision rectification. The below shown circuit is the precision full wave ...

U5 and U6 are the optocouplers for this circuit. The top and bottom circuits are identical, so I will focus only with one of them. Power is provided to the circuit by the 17 VAC coming from the ...

In 1991, Kassakian gave, in Example 3.1, a description for a half-wave rectifier [4] and two years later, Tarter showed several mathematical steps. [5] In 2004, Shepherd offer yet another result ...

It is the same circuit as the classic simple precision rectifier (set to pass the negative half-sine), but with the non-inverting input of the op-amp connected to the voltage-to-clamp-to rather than ...
