Abstract
A level shifter which includes an inverter, first/second/third/fourth N-type transistors, first/second P-type transistors and a buffer is provided. The inverter inverts an input voltage to generate an inverted input voltage based on a first reference voltage. The first N-type transistor has a gate receiving the input voltage. The second N-type transistor has a gate receiving the inverted input voltage. The third N-type transistor has a source coupled to a drain of the first N-type transistor. The fourth N-type transistor has a source coupled to a drain of the second N-type transistor. Gates of the first/second P-type transistors are coupled to the drains of the second/first N-type transistors, respectively, and sources of the first/second P-type transistors receive a second reference voltage. The level shifter generates an output voltage according to a shifted voltage on the drain terminal of the third N-type transistor or the drain terminal of the fourth N-type transistor.
