Abstract
A 5-bit fully flash A/D converter (ADC) is built using only n-channel amorphous silicon hydride (a-Si:H) thin film transistors (TFT), metal resistors and capacitors. The circuit is built on silicon using a low temperature process, compatible with flexible plastic substrates. The circuit consumes a power of 13.6 mW running at a speed of 2 k samples/sec. The measurements show reasonably good characteristics, achieving a DNL of less than ±1 LSB and INL of less than ±1.8 LSB without calibration.
