CURRENT RECYCLING FREQUENCY MULTIPLIER

摘要

PROBLEM TO BE SOLVED: To obtain a current recycling frequency multiplier capable of reducing the influence of inductance in grounding wiring. SOLUTION: A differential input terminal IN1 is connected to one differential output terminal of a VCO, and a differential input terminal IN2 is connected to the other of the VCO. RF signals that are outputted from the VCO and are complementary each other are inputted to the differential input terminals IN1, IN2 as input signals. The gate of an n-channel MOS transistor M1is connected to the differential input terminal IN1, and that of an n-channel MOS transistor M2is connected to the differential input terminal IN2. Each source of the n-channel MOS transistors M1, M2is connected to grounding potential. Each drain of the n-channel MOS transistors M1, M2is commonly connected to a node N1.
