Abstract
This paper presents a fully integrated CMOS low-IF receiver working at L-band for DAB application. An image-rejection low noise amplifier (LNA) supplies over 30dB image rejection in the whole band. A calibration circuit improves matching of quadrature LO signals. Together with the quadrature weaver architecture, the receiver rejects the image signal more than 65dB. The receiver´s noise figure is 4dB and OIP3 is 22dBm. The receiver is implemented in 0.25μm CMOS process. The core die area is 9mm2.
