【Abstract】 A novel CMOS source-follower buffer circuit is presented,which has a faster drivability for large capacitance loads than the tapered inverter chains,due to the characteristic of the CMOS source follower.When driving the large capacitance that is 100 times/6000 times as high as the original capacitance by an elemental inverter,two-stage combined source-follower/inverter buffer is 15% faster than the faster tapered inverter-chain buffer of eight-stage,with smaller wafer area.This circuit structure is simple and can be realized by the standard CMOS process easily.更多还原
