This work analyzes the implications of noise coupling in arrays of antennas on the design of
low-noise amplifiers (LNAs). To select LNA design parameters in a manner familiar to LNA …

Researchers have described the concept of noise matching since at least the 1950s, with
studies demonstrating the interrelationships among the noise factor of a low-noise amplifier …

The inequality relating F min and Lange invariant N for any noisy linear two-port network has
been known since the 1980s. However, the applicability of this inequality to MOSFETs is not …

New equations for circles of constant noise measure in the source reflection coefficient
plane are presented, and these are used to derive closed-form expressions for the minimum …

This paper describes a method for characterizing mixer noise in terms of several noise
parameters. A measurement method for extracting the noise parameters is proposed and …

This paper reports a novel systematic theory of the noise invariants of two-port linear noisy
networks under lossless reciprocal input and output impedance transformations. The theory …

This paper describes a new procedure to extract the noise parameters of on-wafer devices.
The procedure is based on multiple noise figure measurements of similar devices of different …

Noise parameters are used to characterize noise performance of linear devices, such as
amplifiers. Such noise parameters have not been used for frequency conversion devices …
