Abstract
An integrated circuit which includes a pre-driver configured to receive a first high supply voltage and to generate an input signal and at least one post-driver configured to receive at least one second high supply voltage and to receive the input signal. The at least one post-driver includes an input node configured to receive the input signal and an output node configured to output an output signal. The at least one post-driver further includes a pull-up transistor configured to be in a conductive state during an entire period of operation, and a pull-down transistor. The at least one post-driver further includes at least one diode-connected device coupled between the pull-down transistor and the output node. Each post-driver of the at least one post-driver is configured to supply the output signal having a second voltage level corresponding to a high logic level which is higher than an input voltage level.
