Abstract:
In an embodiment, a circuit for tripling frequency is 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 that are cross-coupled, and a trans-characteristics f(Vin) approximating a polynomial nominal trans-characteristic given by
