Single-Pin Driver: An Output Driver Boosting Technique for Off-Chip Bus

A new circuit technique named Single-Pin Driver(SPiD) is proposed. This circuit behaves like a bus terminator with negative capacitance and can be used for enhancing the switching speed of off-chip drivers, or for reducing the simultaneous switching noise by allowing smaller off-chip drivers under the same speed constraint. Experimental results show 10-50% improvement in the rise and fall times under typical loading conditions with a 1.0¿m CMOS technology.
