Abstract

A circuit (12), comprising: frequency multiplier circuitry (120) having input nodes (INp, IN_N) configured to receive an input signal (V_f0) and an anti-phase version thereof, the input signal (V_f0) having a first frequency value, the frequency multiplier circuitry (120) configured to produce a current signal (i_2f0) at a second frequency value that is an even multiple of the first frequency value; a transformer (122) comprising a primary side (Lp, Cp) and a secondary side (Ls, Cs), wherein the primary side (Lp, Cp) of the transformer (122) comprises a primary inductance (Lp) coupled (126) to the frequency multiplier circuitry (120) to receive the current signal (i_2f0) therefrom, wherein the secondary side (Ls, Cs) of the transformer (122) is configured to provide a frequency multiplied voltage signal (V_OUT); wherein the frequency multiplier circuitry (120) and the transformer (122) are cascaded between at least one first node (D) and a second node (S), the at least one first node (D) and the second node (S) configured to be coupled to a supply node (VDD) and ground (GND); a first shunt resonator (124a) coupled between the supply node (VDD) and the at least one first node (D); a second shunt resonator (124b) coupled between the second node (S) and ground (GND), and a bypass current path (126) coupled between the at least one first node (D) and the second node (S).
