Abstract
A pulsed voltage amplification device with drift correction comprises a main differential amplifier whose non-inverting input is coupled to a pulsed voltage source, this main differential amplifier being provided with a pulsed feedback circuit coupled to the output and the inverting input of the main differential amplifier, and a memory capacitor coupled to the inverting input of the main differential amplifier. The pulsed feedback circuit comprises an additional differential amplifier, having its non-inverting input coupled to the output of the main differential amplifier, and a diode connected in series with the additional differential amplifier and coupled to the inverting input of the main differential amplifier. The operation of the proposed device in conjunction with various amplitude analyzers makes it possible to enhance the validity and accuracy of the analysis results, to simplify circuit requirements and to increase circuit reliability.
