Patent ID: 7233201

Claim:
A pseudo-differential driver circuit, comprising: a first transistor having a gate coupled to receive a first part of a differential signal; a second transistor having a gate coupled to receive a second part of the differential signal varying opposite the first part of the differential signal, a source of the second transistor coupled to a source of the first transistor; a pull-down circuit coupling the source of the first transistor and the source of the second transistor to a ground voltage; a single-ended pseudo-differential output coupled to a drain of the second transistor; a supply voltage coupled to a drain of the second transistor; and a third transistor directly electrically coupling the supply voltage to a drain of the first transistor such that the third transistor's source is directly electrically coupled to the supply voltage and the third transistor's drain is directly electrically coupled to the first transistor's drain, the third transistor gate coupled to a control signal operable to cause approximately the same current to flow through the first transistor and the second transistor.
