Optimum millimetre-wave amplifier design using scalable models for circuit elements

A design method for a millimetre-wave amplifier using accurate and scalable models extracted from the measured S-parameters of each circuit component is presented. The amplifier was fabricated using low-cost CMOS technology. The measured results show that the figure of merit of the fabricated amplifier - taking into account gain, noise figure, power consumption and size - is 177 which verifies the ability of the presented method for millimetre-wave amplifier design. The sensitivity of the amplifier performance with respect to the design parameters is also presented.
