ELECTRONIC CIRCUIT FOR TRIPLING FREQUENCY, IN PARTICULAR FOR RADIOFREQUENCY APPLICATIONS IN THE MILLIMETER WAVE RANGE

摘要

A circuit for tripling frequency configured to receive an input voltage (Vin) having a sinusoidal shape and a base frequency. The circuit has a first and a second transistor pair (Q1-Q4) that are cross-coupled and a trans-characteristic f(Vin) approximating a polynomial nominal trans-characteristic (1) :fVin=3AVin−4A3Vin3gm ]]> wherein gm is a transconductance of transistors of the first and second transistor pairs.
