Abstract:
A switch driver circuit includes a plurality of pullup transistors. The plurality of pullup transistors includes a first pullup transistor coupled between a voltage supply and a first output node. A plurality of pulldown transistors includes a first pulldown transistor coupled between the first output node and a ground node. A slope control circuit is coupled to the ground node. A plurality of global connection switches includes a first global connection switch coupled between the first output node and the slope control circuit.
