ABSTRACT:
A first current controlled oscillator outputs an oscillation signal of a first frequency equal to a product of a first control current and a first gain. A first voltage/current converting circuit outputs a first output current equal to a product of a second gain and a voltage difference between a first control voltage and a first reference voltage. A first reference current generator outputs a constant current. A control current circuit outputs a second output current variable. An adder sets the first control current to a sum of the first output current, the constant current and the second output current.
