Classification: CPC H | IPC H

Claim 16:
17. The transmit driver circuit of claim 15, wherein:
the driver unit cell in each DAC driver slice further comprises a second pull-up transistor and a second pull-down transistor having a drain coupled to a drain of the second pull-up transistor;
each DAC driver slice further comprises a second predriver having a first output coupled to a gate of the second pull-up transistor and having a second output coupled to a gate of the second pull-down transistor;
the second predriver comprises:
a third inverter having an input coupled to a common input node of the second predriver and having an output coupled to the first output of the second predriver; and
a fourth inverter having an input coupled to the common input node of the second predriver and having an output coupled to the second output of the second predriver; and

transistors in at least one of the third inverter or the fourth inverter have different strengths.
