Buffer circuit between different voltage domains
A circuit includes a first inverter and a second inverter. The first inverter is coupled to an input terminal. The input terminal receives an input signal varying in a first voltage domain. The second inverter is coupled between the first inverter and an output terminal. The second inverter generates an output signal varying in a second voltage domain. The first inverter includes a first PMOS transistor and a first NMOS transistor. The first PMOS transistor is biased by a first input tracking signal generated from the input signal. The first input tracking signal varies in a third voltage domain. The first NMOS transistor is biased by a second input tracking signal generated from the input signal. The second input tracking signal varies in the second voltage domain.
