Abstract:
1. An apparatus, comprising: a plurality of source followers, each of the plurality of source followers comprising a pull-down transistor having a source, a drain, a gate, and a bulk terminal; a plurality of pull-up transistors, each of the plurality of pull-up transistors having a source, a drain, and a gate, wherein the drain of each of the plurality of pull-up transistors is coupled to the source of a pull-down transistor of the plurality of source followers, to output a plurality of differential signals via the drains of the plurality of pull-up transistors; a first current source coupled to the sources of the plurality of pull-up transistors, wherein the first current source is powered by a first voltage of at least about 1.624V to 2.725V; an operational amplifier, coupled to the first current source, to drive the first current source; and a feedback path coupled between the drains of the plurality of pull-up transistors and an input of the operational amplifier.
