Abstract :
This paper presents a trial fabricated GaAs monolithic anti-series varactor pair. Its second-order and third-order harmonic distortions, which are generated from the nonlinearity of capacitance-voltage characteristics, are investigated experimentally and numerically. Compared to the case of a single varactor, the distortions of measurement and simulation are suppressed by about 25 dB and 45 dB for the second-order harmonic, and 3 dB and 10 dB for the third-order harmonic, respectively.
