Abstract

The image rejection mixer for Digital Audio Broadcasting and Digital Multimedia Broadcasting (DAB/DMB) is described. The mixer is implemented in a 0.18μm six-layer metal CMOS process and occupies a 2.25mm2. To obtain the ultimate level of image rejection without additional tuning, the double quadrature architecture is used and to linearize the RF buffer, differential transconductance linearization technique is used [6]. The fabricated mixer exhibits 65 dB image rejection ratio, 41dB adjacent channel rejection ratio, 100 kHz ∼ 1.65MHz image rejection bandwidth, 16dB gain, 35dBmV input-referred third order intercept point (IIP3), and 15mA current consumption from 1.8V supply.
