Abstract
Possible approaches to designs of the high linearity differential SQUID arrays and SQIF structures are suggested and discussed. The spectrum analysis technique has been applied to the problem solution. Differential scheme of two series arrays of interferometer cells with abs(sin(x))-like voltage response has been suggested to meet the requirement on the highly linear voltage response of the structure. The differential coupling allows an automatic cancellation of the even spectrum components that degrade the linearity of the array voltage response. If interferometer cells are replaced by parallel arrays, the parallel-series structure provides much higher performance of the voltage response. The differential structures allow designing of wide-band high-linear amplifiers for gigahertz frequency range. A traveling wave differential amplifier design is suggested to avoid limitations resulting from distributive character of the long series array.
