PHASE ERROR COMPENSATION CIRCUIT

摘要

A method and a system of compensating for phase error are disclosed. A phase error compensation circuit is configured to generate a corresponding phase-corrected in-phase (I) output signal corresponding to a phase-corrected quadrature (Q) output signal, the circuit includes a first mutual conductance circuit configured to convert a voltage signal related to an I input voltage signal into an I current signal. A second mutual conductance circuit is configured to convert a voltage signal related to a Q input signal into a Q current signal. A first multiplier circuit is configured to multiply the Q current signal by a Q scaling constant. A second multiplier circuit is configured to multiply the I current signal by an I scaling constant. An I adder adds the I current signal to the scaled Q signal. A Q adder adds the Q current signal to the scaled I signal.
