Abstract:
A system for correction of the phase error in in-phase and quadrature signals may include a first signal and a second signal. The system includes a first circuit and a second circuit, each circuit configured for receiving a square-wave input signal and supplying a respective square-wave output signal. The output signal is delayed with respect to the input signal and each circuit is configured in such a way that the propagation delay of a rising edge and the propagation delay of a falling edge between the input signal and the output signal are configurable. The first circuit is configured for receiving the first signal, and the second circuit is configured for receiving the second signal.
