A self-healing 60-GHz transceiver architecture which employs information collected from on-chip sensors to intelligently adjust various tuning knobs and significantly improve the post-healing performance yield is discussed. The analog-to-digital converter (ADC) and digital-to-analog converter (DAC) form the primary interfaces between a transceiver and the digital baseband processor. The ADC and DAC generate a noise-like distortion due to quantization of analog signal levels for digital representation. The synthesizer generates the RF references used for up/down conversion in the transceiver. To ensure robust healing in the presence of noise, the parameter estimator (PE) performs statistical processing to estimate the mean of p and its covariance matrix Pcov, which provides a reliability measure of p. On the basis of these measurements, the PE estimates the impairment parameters, and the cautious dual controller uses Pcov to find the optimum knob settings.
