1. An imaging system, comprising:
a detector substrate;
a capacitor coupled to the detector substrate and configured to store charge from the detector substrate during a charge collection operation;
a switch coupled to the capacitor and configured to selectively electrically connect the capacitor such that the charge stored on the capacitor is read out through the switch during a readout operation; and
a programmable current source coupled to the capacitor and configured to provide charge to the capacitor.
