Abstract
A multiple-finger off-chip driver (OCD) uses delay between branches of the output stage. The delay between branches is controlled using bias circuitry which compensates for process, temperature, and voltage (PVT) variations, resulting in less variation of slew rate at the output of the OCD. The OCD includes a time domain delay stage; a pre-driver stage; a final driver stage; and a bias circuit, for providing bias voltages to the time domain stage that compensate for process, temperature and voltage (PVT) variations on the time domain stage.
