Abstract
The invention provides a voltage-generating circuit with a simple configuration capable of saving space and generating reliable voltage. The voltage-generating circuit of the invention includes a reference voltage-generating unit, a PTAT voltage-generating unit, a comparison unit, and a selection unit. The reference voltage-generating unit generates a reference voltage essentially without dependency on temperature. The PTAT voltage-generating unit generates a temperature-dependent voltage with a positive or negative dependency on temperature. The temperature-dependent voltage is equal to the reference voltage at a target temperature. The comparison unit compares the reference voltage with the temperature-dependent voltage. The selection unit selects and outputs either the reference voltage or the temperature-dependent voltage.
