ABSTRACT:
A level shifter circuit and method of operating therefor. The level shifter circuit is coupled to receive a data signal via an input circuit, wherein the input circuit is in a first voltage domain. The level shifter circuit is also coupled to receive a clock signal from a second voltage domain. On a first portion of the clock cycle, true and complementary output nodes of the level shifter circuit (which are in the second voltage domain) are pulled to a first voltage by activation of respective pull transistors. On a second portion of the clock cycle, one of the true or complementary output nodes is pulled to a second voltage on a second voltage node by enabling the supply to the latch. Data is captured by the keeper, outputting true and complementary versions of the data signal in the second phase of the clock.
