A switched input circuit structure of the type which includes an input terminal receiving an input voltage and an output terminal connected to an input capacitor. An operational amplifier is included having a non-inverting terminal connected to a ground reference terminal, an inverting input terminal, and an output terminal feedback connected to the inverting input terminal and held in a virtual ground condition by a parallel of first and second charge paths which are connected between the input terminal of the switched input circuit structure and the inverting input terminal of the operational amplifier and connected to the supply voltage reference and the ground reference, respectively.

Abstract

A switched input circuit structure of the type which includes an input terminal receiving an input voltage and an output terminal connected to an input capacitor. An operational amplifier is included having a non-inverting terminal connected to a ground reference terminal, an inverting input terminal, and an output terminal feedback connected to the inverting input terminal and held in a virtual ground condition by a parallel of first and second charge paths which are connected between the input terminal of the switched input circuit structure and the inverting input terminal of the operational amplifier and connected to the supply voltage reference and the ground reference, respectively.

The Electrical and Electronics Engineering category covers resources concerned with applications of electricity, generally those involving current flow through conductors, as in motors and generators. This category also covers the examination of the conduction of electricity through gases or a vacuum as well as through semiconducting materials. Topics include image and signal processing, electromagnetics, electronic components and materials, microwave technology, and microelectronics.
