Abstract:
A reference current generation circuit is provided, in which a current generated according to a bandgap voltage is not directly used as a reference current, but the current generated according to the bandgap voltage is used to adjust an output reference current. In this way, the reference voltage is generated without using an external resistor, so as to effectively decrease the production cost.
