Abstract
In an embodiment, a circuit for tripling frequency is configured to receive an input voltage (V) having a sinusoidal shape and a base frequency. The circuit has a first and a second transistor pair that are cross-coupled, and a trans-characteristics f(V) approximating a polynomial nominal trans-characteristic given by where A represents an amplitude of the input voltage and gis a transconductance of transistors of the first and second transistor pairs.
