A sinusoidal signal multiplier circuit produces an output sinusoidal signal substantially without any DC component. This sinusoidal signal multiplier circuit includes a first multiplication cell receiving a first sinusoidal signal at a first input and a second sinusoidal signal at a second input. The first multiplication cell delivers a first output signal. The sinusoidal signal multiplier circuit also includes a second multiplication cell, identical to the first multiplication cell, that receives the second sinusoidal signal at its first input and the first sinusoidal signal at its second input, and delivers a second output signal. The sinusoidal signal multiplier circuit also includes an adder circuit to add the first output signal and the second output signal to provide from the sinusoidal signal multiplier circuit an output signal substantially without any DC component.
