Classification: CPC H | IPC H

Claim 14:
15. A transmit driver circuit comprising:
a plurality of digital-to-analog converter (DAC) driver slices, each DAC driver slice comprising:
a driver unit cell comprising a first pull-up transistor and a first pull-down transistor having a drain coupled to a drain of the first pull-up transistor; and
a first predriver having a first output coupled to a gate of the first pull-up transistor and having a second output coupled to a gate of the first pull-down transistor, wherein:
the first predriver comprises:
a first inverter having an input coupled to a common input node of the first predriver and having an output coupled to the first output of the first predriver; and
a second inverter having an input coupled to the common input node of the first predriver and having an output coupled to the second output of the first predriver; and

transistors in at least one of the first inverter or the second inverter have different strengths.
