—A nonrecursive digital calibration technique, namely, local oscillator (LO) switching, is proposed for jointly eliminating transmitter (TX) and receiver (RX) I/Q imbalances in one combined process. The add-on analog parts are limited to a set of source followers (0.00228 mm 2) and metal–oxide–semiconductor (MOS) switches (0.00017 mm 2) for reusing the 90 •(More)
