A 10b linear interpolation DAC using body-transconductance control for AMLCD column driver

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 0.35LSB on 10b accuracy, respectively. Each channel of driver IC has a height of 295μm, a pitch of 14μm and a static current of ΙμΑ The fabricated chip… (More)
