ABSTRACT:
At least a first base signal and a second base signal are mutually in quadrature and both are capable of mutually exhibiting a quadrature error. These signals are used to formulate two pairs of delayed signals that includes a first delayed signal that is delayed with respect to the first base signal, a second signal delayed in phase opposition with respect to the first delayed signal, a third signal delayed with respect to the second base signal, and a fourth delayed signal in phase opposition with respect to the third delayed signal. The value of each of the delays is continuously adjusted using two differential signals arising from a direct or an indirect cross-mixing of the two pairs of delayed signals to obtain the four delayed signals virtually in quadrature.
