Pre-charged high-speed level shifters

摘要

An integrated circuit structure includes a latch having a first output node and a second output node complementary to each other. A first pre-charge transistor has a source-drain path coupled between a positive power supply node and the first output node. A second pre-charge transistor has a source-drain path coupled between the positive power supply node and the second output node. The integrated circuit structure further includes a delay-inverter coupled between a signal input node and inputs of a first NMOS transistor and a second NMOS transistor in the latch. The delay-inverter is configured to allow one of the first pre-charge transistor and the second pre-charge transistor to pre-charge a respective one of the first output node and the second output node before an input signal at the signal input node arrives at a gate of a respective one of the first NMOS transistor and the second NMOS transistor.
