Abstract
Disclosed is a voltage level converter that includes: a first conversion unit which receives at least one input signal of a logic 1 signal and a logic 0 signal from a signal input terminal and converts the signal; a second conversion unit and a third conversion unit which alternately output a logic −1 signal and the logic 1 signal respectively in accordance with the input signal; a fourth conversion unit and a fifth conversion unit which alternately output the logic −1 signal and the logic 0 signal respectively in accordance with the input signal; and a latch which has a complementary characteristic in which if a first transistor becomes an on-state, then a second transistor becomes an off-state in accordance with the input signal, and performs a positive feedback operation. A drain output of the first transistor is input to the fourth conversion unit. A drain output of the second transistor is input to the fifth conversion unit.
