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.

A wireline transceiver system comprising:
- 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.

A method for generating bias voltages in a wireline transceiver system, comprising:
- generating a signal at a predriver;
- receiving the generated signal at a source-series termination (SST) driver;
- and
- continuously generating the bias voltages in real time at a replica driver 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.
