Voltage repeater circuit for loads with a resistive component with harmonic distortion compensation

摘要

A voltage repeater circuit for loads with a resistive component with harmonic distortion compensation includes first, second and third MOSFET transistors, respectively N-channel, P-channel, and N- channel. The drain electrode of the first transistor whose gate electrode forms an input terminal of the repeater circuit is connected to the positive terminal of a voltage source via a constant current generator and is coupled to the gate electrode of the second transistor by a first circuit designed to establish a constant voltage between these electrodes, and to the gate electrode of the third transistor, by a second circuit designed to generate a constant voltage between these electrodes. The source electrode of the first transistor is connected to the drain electrode of the second transistor and to the drain electrode of the third transistor at a circuit node which forms an output terminal of the repeater circuit. The source electrodes of the second and third transistors are respectively connected to the positive terminal and the negative terminal of the voltage source.
