Title:
CONSTANT VOLTAGE GENERATING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/241257
Kind Code:
A1
Abstract:
This constant voltage generating circuit includes, for example, a first transistor and a second transistor, a first resistor configured to be connected between the gate and source of the first transistor, and a second resistor configured to pass a current having the same value as the current flowing through the first resistor, wherein a first constant voltage is generated using the difference between the gate-source voltages of both the first transistor and the second transistor, and the voltage between the two ends of the second resistor.
