Patent ID: 11777502

Abstract:
A semiconductor device is provided; the semiconductor device includes unipolar transistors. A steady-state current does not flow in the semiconductor device. The semiconductor device uses a high-level potential and a low-level potential to express a high level and a low level, respectively. The semiconductor device includes unipolar transistors, a capacitor, first and second input terminals, and an output terminal. To the second input terminal, a signal is input whose logic is inverted from the logic of a signal input to the first input terminal. The semiconductor device has a circuit structure called bootstrap in which two unipolar transistors are connected in series between the high-level potential and the low-level potential and a capacitor is provided between an output terminal and a gate of one of the two transistors. A delay is caused between the gate of the transistor and the signal output from the output terminal, whereby the bootstrap can be certainly performed.
