Abstract

PURPOSE: To reduce carrier leak to facilitate to make a circuit into an IC by performing modulation by a diode which is provided in the output side of a differential amplifier.
CONSTITUTION: A series circuit where diodes D1 and D4 are connected in series with polarities opposite to each other and a series circuit where diodes D2 and D3 are connected in serieas with characteristics opposite to each other are provided, and one end of the D1 and D4 series circuit and the other end of the D2 and D3 series circuit are connected commonly through resistances R1 and R2, and the other end of the D1 and D4 series circuit and one end of the D2 and D3 series circuit are connected commonly through resistances R4 and R3. Then, signal current ΔIm is supplied to the D1 and D4 series circuit and the D2 and D3 series circuit with phases opposite to each other, and signal current ΔIo is supplied to the connection point of D1 and D4 and the connection point of D2 and D3 with phases opposite to each other, and the product of signal currents ΔIm and ΔIo is taken out at the common connection point. As a result, the signal level can be made small, and carrier leak can be ignored, and the circuit can be made into an IC easily.
