Zusammenfassung:A relatively high-speed, high-efficiency CMOS two branch driver core that may operate under relatively low supply voltage may include thin oxide CMOS transistors configured to generate rail-to-rail output swings larger than twice a supply voltage and without exceeding safe operating area limits. Each of the two branches may include two stacked CMOS inverter pairs configured to drive a respective load capacitance coupled between respective CMOS inverter outputs, in phase opposition to the other branch. A pre-driver circuit input with a differential modulating signal may output two synchronous differential voltage drive signals of a swing of half of the supply voltage and DC-shifted by half of the supply voltage with respect to each other and that may be applied to the respective CMOS inverter inputs of the two branches.
