Abstract:
1. A digital imaging apparatus comprising: a. a detector for generating a first signal in response to photons incident thereupon; and b. readout circuitry operatively coupled to the detector, said readout circuitry configured to generate a second signal representative of said first signal, said readout circuitry including an electron device comprising: the digital imaging apparatus being configured to be operable in two modes of operation, such that in a first mode of operation the first signal is provided at the gate terminal of the field effect transistor, and the current flowing between the drain and source terminals of the field effect transistor results in a signal indicative of the first signal being provided at an output line, and in a second mode of operation, a signal indicative of the first signal is provided at the output line by substantially bypassing the field effect transistor.
