Abstract :
A 10-b interpolation DAC is implemented for AMLCD column driver using 4b control of body potential via a built-in body buffer for interpolation in the buffer amplifier. Measured INL and DNL are 0.36 LSB and 0.35 LSB on 10b accuracy, respectively. Each channel of driver IC has a height of 295 μm, a pitch of 14 μm and a static current of 1 μA. The fabricated chip is in 90n CMOS process.
