  • Reference voltage generating circuit device
    Patent number: 5150188
    Abstract: A reference voltage generating circuit device, which is integrally formed on a semiconductor substrate and an external supply voltage is applied thereto, includes a resistor having a first terminal connected to a first supply terminal, which becomes high potential, at least one diode connected between a second terminal of the resistor and a second supply terminal, which becomes low potential, in a forward direction, and at least one second diode connected to the resistor in parallel and connected to the first diode in series and a forward direction, wherein a reference voltage is generated from a node between the first diode and the second diode.
