US 2021/0280252 A1 · SEMICONDUCTOR DEVICE

Abstract

A semiconductor device includes a level conversion circuit. The level conversion circuit includes a first transistor, a second transistor, a current limiting element, and a voltage adjusting circuit. The first transistor includes a gate connected to an input node. A signal corresponding to a first power supply voltage is input to the input node. The second transistor has a source connected to a drain of the first transistor, a drain connected to a second power supply voltage that is higher than the first power supply voltage, and a gate connected to a first node. The current limiting element is electrically connected between the first node and an output node. The voltage adjusting circuit adjusts a voltage of the first node in accordance with the signal input to the input node.
