Abstract
Various embodiments relate to an adaptive linear driver, including: a continuous time linear equalizer (CTLE); a programmable transmit driver coupled with an output of the CTLE, wherein the transmit driver includes a first control port configured to receive a first control signal configured to adjust the output level of the programmable transmit driver; an output comparator coupled to an output of the programmable transmit driver, wherein the output comparator is configured to compare the output of the programmable transmit driver with a reference signal and to produce a first comparison signal; and a controller coupled to the output comparator and the first control port, wherein the controller produces a first control signal based upon the first comparison signal.

An adaptive linear driver, comprising:
- a continuous time linear equalizer (CTLE);
- a programmable transmit driver coupled to an output of the CTLE, wherein the programmable transmit driver includes a first control port configured to receive a first control signal to adjust an output level of the programmable transmit driver;
- an output comparator coupled to an output of the programmable transmit driver, wherein the output comparator is configured to compare the output of the programmable transmit driver with a reference signal and to produce a first comparison signal;
- and
- a controller coupled to the output comparator and the first control port, wherein the controller produces the first control signal based upon the first comparison signal and provides the first control signal to the programmable transmit driver.
