Abstract:
1. An inverter circuit, comprising: an input stage coupled to a first voltage source providing a first voltage, the input stage being configured to receive an input signal and to provide a first control voltage and a second control voltage in response to voltage variations in the input signal; and an output stage configured to provide an output signal providing a voltage which varies between a second voltage and a third voltage in response to the first control voltage and the second control voltage; wherein the input stage includes first and second complementary pairs of transistors, the first complementary pair of transistors directly coupled together at a common node that receives the first voltage, and the second complementary pair of transistors directly coupled together at the common node to receive the first voltage; wherein a voltage of the input signal varies between the second voltage and the third voltage; wherein the first control voltage varies between the first voltage and the second voltage; and wherein the second control voltage varies between the first voltage and the third voltage.
