Phase calibration technique for mismatch optimization in image-reject receivers
2006 (English)In: Analog Integrated Circuits and Signal Processing, ISSN 0925-1030, E-ISSN 1573-1979, Vol. 46, no 2, 165-168 p.Article in journal (Refereed) Published
This paper presents phase calibration technique without using any external tone for weaver image-reject receiver. Error signal (phase mismatch information) is generated using a simple algorithm and this signal is used for mismatch elimination. Calibration system has been implemented using simulink which shows an image rejection ratio of 59.5 dB can be achieved for RF signal operating at 1.8 GHz.
