Abstract:
In a circuit for converting sensory data to an electrical signal, of the type including a sensor, an amplifier connected such that an output of said sensor controls said amplifier, and a sensor reset connected to the sensor for selectively resetting a charge state of said sensor, an improvement comprising:said sensor reset including a reset transistor, said reset transistor having a channel region formed of a conductive material having a first structural state;said amplifier including an amplifier transistor, said amplifier transistor having a channel region formed of a conductive material having a converted first structural state, said amplifier transistor and said reset transistor being formed on a shared substrate; anda synchronizing circuit which applies a bias voltage to said amplifier transistor only at a time when said amplifier transistor is caused to read out a signal.
