摘要

Area-efficient resistor-capacitor DACs (R-C DACs) and low-offset push-pull output buffers for a 10-bit LCD source driver are proposed. Comparing to a 10-bit resistor-string DAC (R-DAC), the 10-bit R-C DAC has a smaller area. A new output buffer with a push-pull function is adopted so that the source driver can drive the pixel with two-dot inversion to save power consumption. To reduce channel to channel deviations, an offset averaging method is adopted in this work. The simulated settling time is under 7μs so it is suitable for UXGA LCD TV applications. The chip is fabricated using the TSMC 0.35μm 2P4M CMOS process. The chip area is 1704x262 μm2.
