Abstract

See full text

In one embodiment of the present invention, a drive circuit includes: a logic block connected between a source of a first voltage and a source of a second voltage, and a sampler including a plurality of sampling circuits. Each sampling circuit is for sampling, in use, an input data signal and outputting a voltage to a respective output. The drive circuit further includes a voltage booster having plurality of voltage boost circuits, each voltage boost circuit being associated with a respective one of the sampling circuits and, in use, generating a boosted voltage signal and providing the boosted voltage signal to the respective sampling circuit. Each voltage boost circuit is connected between the source of the first voltage and the source of the second voltage. The logic block may be, but is not limited to, a shift register.
