Monolithic RF Mixers
Mixers are very important building blocks in any RF systems. Downconversion mixers link together the low-noise amplifier, local oscillator and IF stage of which the performances are interrelated. Their highly nonlinear behavior makes analysis and optimization difficult. This behavior can cause noise and spurious signals to move across frequencies.
A large amount of effort has been expended by group researchers in the design and optimization of monolithic RF mixers. Current work is being carried out in Bipolar, CMOS and BiCMOS technologies. Systematic ways that will provide close-to-optimal active mixer designs are being investigated. New low power techniques such as class AB mixers have been demonstrated. Work on self-calibrated image-reject mixers may provide an interesting way to improve system integration.
