A Novel Design and Optimization Approach for Low Noise Amplifiers (LNA) Based on MOST Scattering Parameters and the gm/ID Ratio

This work presents a new design methodology for radio frequency (RF) integrated circuits based on a unified analysis of the scattering parameters of the circuit and the gm/ID ratio of the involved transistors. Since the scattering parameters of the circuits are parameterized by means of the physical characteristics of transistors, designers can optimize transistor size and biasing to comply with the circuit specifications given in terms of S-parameters. A complete design of a cascode low noise amplifier (LNA) in MOS 65 nm technology is taken as a case study in order to validate the approach. In addition, this methodology permits the identification of the best trade-off between the minimum noise figure and the maximum gain for the LNA in a very simple way.

Formative Assessment and Classroom Activities of New Era Microwave Engineering Curriculum

Microwave engineering (ME) is a technology-based course. The aim of this course is to train future professional engineers to gain practical skills, such as RF-integrated circuits design and analysis, as well as microwave instrument operation. Therefore, the curriculum for this course needs to revise and meet the needs of the future so that future graduated engineers in the telecommunication field can find the job easier and have the professional skills required by the employer. This chapter proposes and presents some simple practical assignments for undergraduates to complete their assessment in the ME course. At the same time, the gap between the university's curriculum and the current development of microwave technology in the industrial sector can be reduced through such practical assignments.
