Abstract :
A 6-bit current steering D/A converter (DAC) is built using only n-channel amorphous silicon (a-Si:H) thin film transistors (TFT) and capacitors. The circuit is built on silicon using a low temperature process, compatible with flexible plastic substrates. The measurements show reasonably good characteristics, achieving a DNL of less than ±1.2 LSB and INL of less than ±1.8 LSB without calibration, at a conversion rate of 500 Hz.
