Abstract :
A 7-bit switched capacitor 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 both plastic and glass using a low temperature process, compatible with flexible plastic substrates. The measurements show excellent characteristics, achieving a DNL of less than ±0.6 LSB and INL of less than ±1 LSB without calibration, at a conversion rate of 500 Hz.
