Abstract
A level shifter circuit includes: K level shifter units for receiving K input signals having a first voltage level range and outputting K output signals having a second voltage level range, wherein the second voltage level range is greater than the first voltage level range. Each level shifter unit is utilized to output an output signal at an output end and includes: a first switch, coupled between the output end and a first voltage source for controlling the electrical connection between the first voltage source and the output end according to an input signal; and (K−1) second switches, connected in parallel between the output end and a second voltage source, for respectively controlling its ON/OFF status according to (K−1) output signals except for the output signal. K is an integer.
