Title:
SEMICONDUCTOR DEVICE, ELECTRICAL STORAGE DEVICE, AND METHOD FOR OPERATING SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/005439
Kind Code:
A1
Abstract:
Provided are novel oscillator, amplifier circuit, inverter circuit, amplifier circuit, battery control circuit, battery protection circuit, electrical storage device, semiconductor device, electrical equipment, and the like. This semiconductor device has a first transistor including a metal oxide and an oscillator including second to fifth transistors, wherein the first transistor is turned to an ON state, a first potential is applied to the gate of the second transistor and to the gate of the third transistor, then the first transistor is turned to an OFF state, the first potential is retained, the oscillator provides to a first circuit a first signal corresponding to the first potential, and the first circuit performs reshaping and/or amplification of the first signal. The second transistor and the fourth transistor are serially connected to each other, the third transistor and the fifth transistor are serially connected to each other, the source or the drain of the third transistor is electrically connected to the gate of the fourth transistor, and the source or the drain of the fourth transistor is electrically connected to the gate of the third transistor.
