Title:
CONSTANT VOLTAGE GENERATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/172001
Kind Code:
A1
Abstract:
Provided is a constant voltage generation circuit having high output voltage precision. The constant voltage generation circuit (1) has: a depression-type first transistor (M1) and an enhancement-type second transistor (M2) that form an ED-type reference voltage source; and a resistor (R1) connected between the gate and the source of the first transistor (M1). The first transistor (M1) and the second transistor (M2) are, for example, NMOSFETs. Moreover, for example, the drain of the first transistor (M1) is connected to an input-voltage (VIN) application terminal, the source of the second transistor (M2) is connected to a reference potential terminal, and the gates of each of the first transistor (M1) and the second transistor (M2), and the drain of the second transistor (M2), are connected to a constant voltage (VREF) output terminal.
