Abstract: First signal processing is applied to a first input signal oscillating at an input frequency and a first set of control signals to generate a first output signal oscillating at a multiple of the input frequency with an amplitude controlled by a control signal in the first set of control signals. Second signal processing is applied to a second input signal oscillating in quadrature at the input frequency and a second set of control signals to generate a second output signal that oscillates at the multiple of the input frequency with an amplitude controlled by a control signal in the second set of control signals. A further output signal, generated in response to the first and second output signals, oscillates at the multiple of the input frequency with a phase shift controlled by a ratio of control signal amplitudes for the first and second sets of control signals.
