Abstract
An embedded DAC requires a large number of input transistors (=2N+1 for N-bit interpolation) in its amplifier. Moreover, the transistors require large width and length for accurate matching, leading to an area penalty in the amplifier for high bit interpolation (e.g. N>3). In this paper, an area-efficient and accurate interpolation method that uses variable-current control (VCC) for 10b mobile AMLCD column drivers is presented.
