Abstract :
The effect of the C/sub max//C/sub min/ ratio on the performance of planar back-to-back Barrier-N-N/sup +/ (bbBNN) frequency multipliers is studied. A simplified physical model of the device is used to relate the electrical characteristics to the material and the structural parameters. Multiplication efficiency is evaluated using a large signal analysis approach. Results indicate that if the optimum device size for a given frequency is used, a high C/sub max//C/sub min/ ratio results in high efficiency.<>
