Higher operating frequencies and greater power demands have increased the requirements on the power and ground network. Simultaneously, due to the larger current loads, current densities are increasing, making electromigration an important design issue. The optimal wire width for an interdigitated power and ground network is based on the resistive and inductive (both self- and mutual) impedance. In...
This paper discusses the design of a 60 GHz low noise amplifier (LNA) using a standard low power SOI CMOS process from ST Microelectronics. First, we outline the technology as well as the mm-wave design challenges. Using recent work on coplanar waveguide (CPW) modeling, we describe how it's possible to use parametric, 3D electromagnetic simulation to complete or replace analytical models of on-chip...
Continuous scaling, necessary for enhanced performance and cost reduction, has pushed existing CMOS materials much closer to their intrinsic reliability limits, forcing reliability engineers to get a better understanding of circuit failure. This requires that designers will have to be very careful with phenomena such as high current densities or voltage overshoots. In addition to the reliability issues,...
A method for preparing permalloy films by electrodeposition using a square-wave pulse-mode current was studied, along with the magnetic properties of the resulting films. The influence of three plating parameters (duty cycle ratio, frequency, and dc bias) on the formation of film structures, alloy composition, and magnetic properties was investigated. It was found that films with ??i??4000 (max. 6000)...
