摘要： Provided is a technology capable of preventing arithmetic operation accuracy from deteriorating even when a bipolar transistor used to form a Gilbert multiplier core has poor characteristics. A correction current generating circuit (3) uses a constant current source (301) to feed a constant current I0 to an emitter of a bipolar transistor (Q7) being a first replica transistor having the same current gain α as bipolar transistors (Q1 to Q4) that form the Gilbert multiplier core (101), to generate a current of α·I0 on a collector side thereof. The current is output as a correction current α·I0, and is added to each of one of input signals (±K1·Vy) of the Gilbert multiplier core (101) as a bias current, to thereby eliminate influence of the current gain α on an output signal being a multiplication result.
