Abstract

With more than 40 years Moore scaling, the speed of CMOS transistors is around 100 GHz. Such fact makes it possible to realize mm-wave circuits in CMOS. However, with the target of achieving broadband and power-efficient operation, 60 GHz CMOS RF transceiver faces severe challenges. After reviewing the technology issues, regarding the 60 GHz applications, this paper discusses design challenges both from the system and the building block levels, and also presents some simulated or measured circuits results.

Abstract

An experiment has been performed to investigate the natural convection heat transfer coupled with the effect of thermal conduction from a steel plate with discrete heat sources. Two boundary conditions, with constant heating flux and constant heating temperature, were obtained by controlling the heating flux or temperature of the heat sources mounted on the back of the plate. The heat transfer and temperature distribution of the plate were measured with different heating spaces. By defining the average heating temperature of the plate as the characteristic temperature, simple expressions for the average heat transfer are correlated from the experimental data as a function of the relative heating space and Rayleigh number. The error is ±5% in the Rayleigh number range from 5 × 10 8 to 5 × 10 9 .
