Abstract
To calibrate the demodulator, a single-tone test signal is also needed. The first section of this chapter describes how to generate this test signal in the modulator. The second section shows the auto-calibration mechanism and calibration circuits design. The error on calibration results caused by the non-ideal calibration circuits and the test signal, and the solution on eliminating the error both will be shown in this section. The final section of this chapter will show the measurement results on the RX modulator calibration.
