ABSTRACT:
An adaptive current generating circuit having a reference voltage supply circuit for supplying a reference voltage subjected to a fluctuation of supply voltage, a reference current supply circuit for supplying reference current responsive to the reference voltage supplied by the reference voltage supply circuit, a control current supply circuit for supplying control current subjected to the fluctuation of the supply voltage and a bias supply circuit for supplying a bias to the reference current supply circuit corresponding to a difference between the reference current supplied by the reference current supply circuit and the control current supplied by the control current supply circuit.
