Abstract
An adaptive sample and hold circuit for signal amplifier range selection is presented. The adaptive sample and hold circuit has an input for receiving an input signal and an output for providing a sample-and-hold-voltage. It also includes a sample-and-hold-capacitor to generate the sample-and-hold-voltage from the input signal, and a range detector. The range detector is adapted to identify a range of the input signal and to adjust a voltage at the sample-and-hold-capacitor based on the range of the input signal to maintain the sample-and-hold-voltage within a predetermined voltage span.
