Abstract:
A signal path linearizer for PAM4 SerDes communications compensates (including pre-compensates) for signal path nonlinearities. The linearizer can be configured with first and second differential gm stages, the first differential gm stage to provide a DC gain, and the second differential gm stage to introduce a defined nonlinear adjustment in DC gain by adding to or subtracting from the DC gain of the first differential gm stage. The differential gm stages can be configured to generate a compensated PAM4 signal with the combined DC gain providing a nonlinear wideband gain adjustment to compensate for nonlinearities in the PAM4 signal path. Compensation range can be increased by selective degeneration, and the compensation region can be shifted by selectively introducing input offset(s).

Claim (Index 2):
The circuit of  claim 1 , wherein:\n the at least first and second differential gm stages configured to generate a compensated PAM4 signal at the differential output port, with the combined DC gain from the first and second differential gm stages providing a nonlinear wideband gain adjustment to compensate for nonlinearities in the PAM4 signal path.
