Abstract
A driver circuit includes a first transistor having a first node coupled to a high supply voltage and a second node coupled to an output node, wherein the first transistor passes the high supply voltage to the output node based on a first gate voltage on a gate of the first transistor. The driver circuit also includes a second transistor having a first node coupled to a low supply voltage and a second node coupled to the output node of the driver circuit, wherein the second transistor passes the low voltage to the output node based on a second gate voltage on a gate of the second transistor. The driver circuit further includes a logic block configured to control a slew rate of an output signal Vout at the output node by controlling a slew rate of the first gate voltage and controlling a slew rate of the second gate voltage.
