Patent ID: 8558604

Claim:
An in-phase, quadrature-phase (IQ) mixer, comprising: a signal provider configured to provide an in-phase (I) mixing signal and a quadrature-phase (Q) mixing signal, wherein a period for the I mixing signal is equal to a period for the Q mixing signal; a controller configured to control the signal provider so that: the I mixing signal is at a first level for an equal number of clock cycles during the period as is the Q mixing signal, the I mixing signal is at a second level for an equal number of clock cycles during the period as is the Q mixing signal, and the I mixing signal is at a null for an equal number of clock cycles during the period as is the Q mixing signal, wherein the null is equal to a remainder of the period that the I mixing signal and the Q mixing signal are not at the first level or the second level; and a clock signal provider configured to provide a clock signal to the signal provider and the controller, wherein the clock cycles are derived from the clock signal.
