Abstract: A wireline transceiver system includes a predriver configured to generate a signal; a source-series termination (SST) driver configured to receive the generated signal; and a replica driver configured to continuously generate bias voltages in real time to modulate current of a push-pull current source of the SST driver based on a voltage of the received signal across a process, voltage, and temperature (PVT) range.

Abstract: A hybrid digital-to-analog converter (DAC) driver is provided. The hybrid DAC driver includes an upper DAC stage configured to receive an upper set of bits of a digital signal, the upper DAC stage comprising an upper set of DAC units, with a first DAC unit in the upper set of DAC units having a different weight than a second DAC unit in the upper set of DAC units; a lower DAC stage configured to receive a lower set of bits of the digital signal, the lower DAC stage comprising a lower set of DAC units formed in an R-2R resistor ladder network; and an output stage for outputting an analog signal from the upper DAC stage and the lower DAC stage.
