In this paper, a unified generic FET frequency multiplier theory is developed. The predictions of this approach are consistent with previously published results, but this theory is valid for an extended set of bias/drive regimes of operation. The mod

A design for a submillimeter quasi-optical multiplier is evaluated both experimentally and theoretically. It is concluded that multipliers should use separate pump and harmonic waveguides to facilitate independent optimisation of the fundamental and

In this paper, an ASIC implementation of a processor for generic computations of the type u = ab/c in the Galois field GF(2m) is described. This algorithm can perform the operations in an Elliptic Curve Crypto (ECC) processor. In this case the hardwa

A circular voltage-controlled phase shifter (VCPS) is proposed to extend the range of the controlled output phase shift unlimitedly. This is made possible by configuring the system to operate in a circular way, differently from the conventional VCPS

The once emerging trend of silicon-on-chip is becoming a reality. The challenge of integrating a digital-to-analog converter on a single chip is one of the bottlenecks in SoC solutions. A threshold inverter quantization (TIQ) architecture is proposed
