A direct conversion transmitter with digital‐assisted DC offset and I/Q phase calibration

Summary A direct conversion transmitter with auto‐calibration mechanism is presented in this paper. Both the carrier leakage and in‐phase/quadrature (I/Q) phase imbalance are compensated by a proposed calibration algorithm to improve transmitter's single‐sideband performance. The digital‐assist...
