Abstract:
1. An integrated circuit comprising a single-ended-to-differential converter comprising: a first series of inverters comprising: a second series of inverters comprising: a first plurality of coupling inverters, each having an input coupled to an output of a respective inverter in the first series and an output coupled to an output of a respective inverter in the second series; a second plurality of coupling inverters, each having an input coupled to an output of a respective one of the respective inverters in the second series and an output coupled to an output of a respective one of the respective inverters in the first series; and a plurality of programmable logic elements configurable to implement user-defined logic functions, wherein the first inverter in the first series of inverters and the first inverter in the second series of inverters receive the input signal from at least one of the programmable logic elements.
