Abstract :
Four non-calibrated image-reject mixer (IRM) architectures have been developed in a 0.35-/spl mu/m 3M2P digital CMOS process. A Weaver, Hartley, and their corresponding double-quadrature topologies have been implemented based on active mixers in order to compare them in terms of achievable image rejection (IR) and low-voltage, low-power operation as part of an ISM (Industrial Scientific Medical) 400-MHz fully Integrated CMOS transceiver for short-range biomedical applications. Monte Carlo simulations over process variation predict image rejection in the range of 65-75 dB for such low-current consumptions as 380-450 /spl mu/A at 1.8 V.
