Capacitor bias recovery methodology

摘要

The present invention provides an apparatus, system and method of improving the bias response time for pre-amplifier circuits that utilize noise reduction capacitors. The system uses a quick recovery circuit electrically connected to the capacitive node of the pre-amplifier circuit (214). The quick recovery circuit (210) comprises a gain amplifier (218) with a resistive input and a controlled current source (225). The controlled current source corresponds to adjustments in a controlled current source of the pre-amplifier and is electrically connected to the resistive input of the gain amplifier. The gain amplifier is selectively switched to operatively connect an output to the capacitive node (235) of the pre-amplifier circuit.
