Abstract:
The results of theoretical and experimental comparison of the signal-conversion efficiency by diodes based on superlattices with a small number of periods ($N$-like current–voltage characteristic) and promising frequency-multiplier diodes (varactors) (parabolic capacitance–voltage characteristic) are presented.
Keywords:diodes based on superlattices, nonlinear current-voltage characteristic, varactor, parabolic capacitance–voltage characteristic, signal-frequency multipliers.
