Abstract

The design and implementation of an on-pixel voltage-controlled oscillator for digital imaging applications based on a ring-oscillator circuit fabricated in amorphous silicon thin-film transistor technology is presented. Preliminary results on sensitivity, voltage to frequency gain, linearity, and simulation results of long-term stability appear promising for its application in large-area digital medical X-ray imagers
