Abstract
In certain aspects, a driver includes a pull-down transistor coupled between an output and a ground, a pull-up n-type field effect transistor (NFET) coupled between a first voltage rail and the output, and a pull-up p-type field effect transistor (PFET) coupled between the first voltage rail and the output. The driver also includes a first switch coupled between a gate of the pull-up NFET and the ground, and a second switch coupled between a gate of the pull-up PFET and a second voltage rail.
