Abstract
A digital CMOS predriver circuit pulls an output node up and down with accurately controlled rise and fall times in the threshold region. Resistors independently set rise and fall slew rates while additional CMOS devices initially charge and discharge the output node. The additional devices turn off before the output reaches the threshold region.
