Silicon RFIC Techniques for Reconfigurable Military Applications.

摘要

The functionality of silicon radio frequency integrated circuits (RFICs) makes the technology particularly suitable for reconfigurable circuits. Designing silicon RFICs requires expertise in the design, simulation and verification of traditional monolithic microwave integrated circuits (MMICs) while also considering a number of requirements unique to silicon RFIC technology. This report shows how MMIC and RFIC design techniques can be combined to yield high performance circuits and a comprehensive design flow for silicon RFICs. This RFIC design flow was validated by designing both linear and nonlinear circuits that were fabricated using a commercial 0.35 micro m SiGe BiCMOS process. These circuits include low noise amplifiers, a voltage controlled oscillator, a double-balanced mixer, a reflection type phase shifter, an analog vector modulator and a 4-bit vector modulator. The two vector modulators generate the variable amplitude and phase weights needed for adaptive phase arrays, which have been proposed to improve the anti-jamming performance of military GPS units.
