Abstract
An in-phase, quadrature phase (IQ) mixer for a near field communications (NFC) device is disclosed that includes a signal provider that provides an in-phase (I) mixing signal and a quadrature phase (Q) mixing signal so that the period of the I mixing signal is equal to a period for the Q mixing signal. A controller is configured to control the signal provider so that the average of the I mixing signal over two periods is minimized and the average of the Q mixing signal over two periods is also minimized. The controller is also configured to control the signal provider so that the average propagation delay for the I mixing signal and the Q mixing signal is minimized individually and relative to each other.
