Abstract
In accordance with a specific embodiment of the present invention, a system is disclosed having an analog to digital converter and control module. The analog-to-digital converter includes an analog input, digital output, and control input. The control input of the analog-to-digital converter is connected to a pulse width modulated output of the control module which provides an offset pulse width modulated signal. During a first portion of the offset pulse width modulated signal a sampling capacitor is charged. During a second portion of the offset pulse width modulated signal an integration capacitor is charged.
