Abstract

See full text

An integrated circuit includes an input circuit coupled to a first voltage supply, and configured to receive a first input signal, and to generate at least a second or a third input signal, and a level shifter circuit coupled to the input circuit and a second voltage supply, and configured to receive a first enable signal, the second or third input signal, and to generate a first signal responsive to the first enable signal, the second or third input signal. The input circuit includes a first set of transistors having a first threshold voltage. The first set of transistors includes a first set of active regions extending in a first direction. The level shifter circuit includes a second set of transistors having a second threshold voltage. The second set of transistors includes a second set of active regions extending in the first direction.
