Abstract
An off-chip driver (OCD) includes: a logic circuit, for providing a logic signal input; a pre-driver stage, coupled to the logic circuit, for providing a ramped up voltage in response to the logic signal input; a final driver stage, coupled to the pre-driver stage, for providing an output voltage in response to the ramped up voltage; and a bias circuit, coupled to the pre-driver stage, for providing a constant bias voltage to the pre-driver stage, wherein the constant bias voltage keeps the pre-driver stage within an operational range to compensate for variations in process, temperature and supply voltage.
