Abstract
A level shifting circuit includes a first inverter, a second inverter, and a third inverter which are connected in a cascade. The first inverter operates at a first power supply voltage supplied to a first power supply line, and the third inverter operates at a second power supply supplied to a second power supply line. The second inverter includes a first p-type transistor having a source connected to the first power supply line, a second p-type transistor having a source connected to the second power supply line, and a first n-type transistor having a source connected to a ground line. Each gate of the first and second p-type transistors and the first n-type transistor is connected to an output terminal of the first inverter, and each drain of the first and second p-type transistors and the first n-type transistor is connected to an input terminal of the third inverter.
