Abstract
The present invention provides an apparatus, system and method of improving the bias response time for pre-amplifier circuits which utilize noise reduction capacitors . The system uses a quick recovery circuit electrically connected to the capacitive node of the pre-amplifier circuit. The quick recovery circuit comprises a gain amplifier with a resistive input and a controlled current source . 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 can be selectively switched to operatively connect an output to the capacitive node of the pre-amplifier circuit.
