Abstract:
1. A voltage mode driver circuit, comprising: a first inverter configured to receive a first input signal at a first input node, invert the first input signal, and output an inverted first input signal at a positive output node; a second inverter configured to receive a second input signal, invert the second input signal and output an inverted second input signal at the positive output node; a first current source configured to provide current to the positive output node via a first switch, wherein the first switch is configured to receive an input at the first input node and where a voltage output swing at the positive output node is larger than a power supply voltage applied to the first current source, wherein the power supply provides the power supply voltage and includes a p-type transistor coupled to an n-type transistor having a drain coupled to ground and to a negative input of an amplifier, the amplifier providing an output serving as an input to the gate of the n-type transistor and the amplifier having the power supply voltage as an input to a positive input of the amplifier.
