Abstract: A circuit for tripling frequency configured to receive an input voltage (V in ) 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(V in ) approximating a polynomial nominal trans-characteristic (1) : f V in = 3 A V in − 4 A 3 V in 3 g m wherein g m is a transconductance of transistors of the first and second transistor pairs.
