摘要
Disclosed herein are novel charge mode readout circuits and associated methods of signal processing. The devices and methods of the invention allow for the improved processing of stored signals by a charge mode readout amplifier, wherein the readout level may be shifted to a desired range and wherein a fully differential output swing may be imparted. The invention advantageously employs a single pair of capacitors to serve the dual roles of modulating amplifier gain and level shifting the output.
