Abstract
The present invention provides a reference voltage generation device which includes a constant current circuit outputting a constant current in response to an input voltage; a voltage generation circuit connected in series to the constant current circuit, using the constant current as an input current, and generating an output voltage based on the input current; and a reference voltage output port outputting the output voltage. In the constant current circuit, multiple depletion type MOS transistors are connected in series, the gate widths are the same, and the sum of the gate lengths is the total gate length of the constant current circuit. In the voltage generation circuit, multiple enhancement type MOS transistors are connected in series, the gate widths are the same, and the sum of the gate lengths is the total gate length of the voltage generation circuit.
