Abstract
A voltage detection circuit and a charge pump circuit using the voltage detection circuit are provided. The voltage detection circuit includes: a voltage raising circuit configured to adjust a voltage to be measured and then output an adjusted voltage, where the adjusted voltage is equal to the sum of the voltage to be measured and a reference voltage; and the reference voltage is generated by a combination of a first voltage with a positive temperature coefficient and a second voltage with a negative temperature coefficient.
