DesignSeminar: RFIC MOS Gilbert Cell Mixer Design
Steve Long, Professor, University of California, Santa Barbara
Abstract: RFIC MOS Gilbert Cell Mixer Design
The Gilbert double-balanced mixer configuration is widely used in RFIC applications because
of its compact layout and moderately high performance. This seminar will walk through the design
of a CMOS Gilbert mixer focusing on the parameters that influence the linearity of the signal path,
the noise, and therefore the spurious-free dynamic range of the mixer. We will explore design
tradeoffs that include biasing and device sizing, LO power, conversion gain, gain compression,
intermodulation distortion, and noise.
