Abstract

A programmable level shifter. The programmable level shifter comprises a first P-type FET, a first N-type FET, a second P-type FET, a second N-type FET, an inverter, and a programmable device. The first P-type FET is coupled between a fist power line and an output node. The first N-type FET is coupled between the first P-type FET and a second power line. The programmable device is coupled between the first power line and the output node, which can be programmed to change an effective resistance between the first power line and the output node when the second P-type FET is turned on.
