Abstract :
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 programming circuit is verified by a polynomial interpolation current-modulation sub-DAC. The polynomial interpolation method provides highly accurate grey-level voltages because of the programming source. The DAC including the programming interpolation cell was implemented in 0.35 μm CMOS process with DNL and INL of 0.43 and 0.40 LSB, respectively.
