摘要： An inverter circuit has a digital signal amplitude converter having an input coupled to an inverter circuit input node, and an amplitude converter output. A positive threshold voltage compensation generator has a positive threshold voltage compensation generator input coupled to the amplitude converter output. A negative threshold voltage compensation generator has a negative threshold voltage compensation generator input coupled to the inverter circuit input node, and a negative threshold voltage compensation generator output. A multiplexer has a first input coupled to the positive threshold voltage compensation generator output, a second input, coupled to the negative threshold voltage compensation generator output, and a multiplexer output. An inverter module has an output providing an inverter circuit output node, and an inverter module input is coupled to the multiplexer output. The inverter circuit at least partially compensates for variations in a threshold voltage associated with switching of transistors that form the inverter module.
