Abstract

This paper presents a design and implementation of an output buffer for LCD Driver with rail-to-rail voltage swing using TSMC 0.35 μm 2P4M process at 5V supply. We designed a class-B output buffer with offset compensation ability to reduce the nonlinearity of output voltage. It performs a rail-to-rail swing range and high slew rate of 14 V / μs and 11.5 V / μs for rising and falling edges under a 400 pF capacitance load. For high driving capability , two push-pull output stages are used , two frequency compensation stages are also introduced for stability , One is the miller compensation with 0.04 pF capacitance , and the other is zero compensation with 0.1 kQ added between two push-pull output stages for stable driving under different capacitance loads. The result exhibits the settling times of 0.7 us for rising and 0.85 μs for falling edges with voltage swing 5V under a 400 pF capacitance load. Even under a 1000 pF capacitance load , it still has the settling time of 1.52 μs and 1.80 μs for rising and falling edges , respectively. The effective area of this buffer is only 100 × 100 μm2 with build-in offset voltage holding capacitor.
