AN ACTIVE QUADRATURE SIGNAL GENERATOR WITH BROADBAND QUADRATURE CHARACTERISTIC

摘要

Disclosed is an active quadrature signal generator with broadband quadrature characteristics. According to one embodiment of the present invention, the quadrature signal generator comprises: a first signal generator outputting an in-phase (I) signal in response to an input signal; a second signal generator connected to the first signal generator to output a quadrature-phase (Q) signal; and a corrector connected between the first and second signal generators and correcting gain and phase of the I signal and Q signal. Each of the first and second signal generators includes an active element.
