Abstract
An apparatus and method. The method includes filtering an output of an in-phase (I-mixer); filtering an output of a quadrature-mixer (Q-mixer); converting an output of a first low pass filter (LPF); converting an output of a second LPF; buffering an output of a first analog-to-digital converter (ADC); buffering an output of a second ADC; buffering a transmitter signal; generating a reference signal from an output of a transmitter (TX) data capture buffer; removing DC from the reference signal; and adaptively tuning an I-mixer digital-to-analog (DAC) code and a Q-mixer DAC code from an output of a first receiver (RX) data capture buffer, an output of a second RX data capture buffer, an output of a DC removal unit, and a predetermined step size for each of the I-mixer DAC code and the Q-mixer DAC code.
