Voltage Multiplier with Diodes and Capacitors

This is a voltage multiplier circuit. This circuit uses a doubler principle to multiply the voltage.  This circuit has some advantages like low current supply, attractive high voltage that is needed for photomultipliers and cathode-ray tubes. Besides that, this circuit is inexpensive. This principle is also used in the Cockroft-Walton accelerator for charged particles the …

OP90 Single Op Amp Full-Wave Rectifier

A full-wave rectifier circuit that provides the absolute value of input signals up to ±2.5 V even though operated from a single 5 V supply is shown in the schematic diagram  below. The amplifier acts as a unity-gain inverter for negative inputs. The op amp output is forced by positive signal to ground. The 1N914 …
