中文摘要	A fully integrated CMOS low-IF weaver receiver working at L-band for DAB (Digital Audio Broadcasting). The receiver takes use of three methods to enhance the image reject performance. Compared with traditional In-phase and Quadrature (I/Q) structure, double quadrature weaver architecture performs higher image reject. An image-reject Low noise Amplifier (LNA) supplies additional image reject in the whole band. The phase and magnitude calibration circuit in LO buffer improves the quadrature of the LO signals. As a result, the receiver can reject the image signal more than 65 dB. The cascade noise figure is 4 dB and OIP3 is 22 dBm. The receiver is fabricated with 0.25 mu m TSMC CMOS technology. The core die area is 9 mm/sup 2/. It is now under test.
