Title:
REFERENCE VOLTAGE GENERATING CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/111994
Kind Code:
A1
Abstract:
A reference voltage generating circuit (1) is provided with: a bandgap reference circuit (2) which generates a first reference voltage (VREF1) that depends on a bandgap reference voltage and a power source voltage (VCC); and a converting circuit (3) which converts the first reference voltage into a second reference voltage (VREF2). The second reference voltage depends on the bandgap reference voltage and a ground voltage (VSS). The ground voltage is lower than the power source voltage.
