The current-mode-based programming interpolation circuit is presented. The proposed circuit can be configured so that any arbitrary number of currents can be generated and independently programmed. The programmingcircuit is verified by a polynomial interpolationcurrent-modulation sub-DAC. The polynomial interpolation method provides highly accurate grey-level voltages because of the programming source. The DAC including the programminginterpolation cell was implemented in 0.35 m CMOS process with DNL and INL of 0.43 and 0.40 LSB, respectively.
