Abstract
In connection with a charge sensing device having a P-N junction and which develops background charge as well as signal charge in the operation thereof, a circuit is provided for reversely biasing the P-N junction and maintaining substantially constant voltage across the P-N junction to balance the background charge developed while sensing signal charge collected by the P-N junction and developing an output proportional to the collected signal charge.
