N2 - In this paper, a 10-bit charge redistributed CMOS D/A Converter is presented for LCD panel driving. The structure of the charge redistributed D/A Converter is consisted of OP-AMP as Unit Gain Sampler, two parallel capacitors, a CMOS switch, and a digital block. In order to solve the capacitor mismatching problem, a compensation method to use alternate capacitors is proposed. Further, the D/A Converter has a digital block to change the digital parallel data into the serial data,which is based on JCCG (Johnson Counter Clock Generator).The chip was fabricated with a 0.35μm 1-poly 4-metal n-well CMOS technology. The effective chip area is 430μm×880μm and it dissipates about 0.607mW power consumption at 3.3V power supply. The INL and DNL is within ±0.41 LSB and ±0.11 LSB,respectively.
