Active Devices in RF Design

This course covers the fundamental and intricate aspects of RF transceiver design, with a focus on active devices used in RF and wireless applications. It provides a comprehensive understanding of different types of active devices, their properties, and applications. The course delves into the classification of these devices based on the semiconductor material used, such as silicon-based and 3v Compound Semiconductor-based devices. It further explains the differences between unipolar and bipolar devices, and the various device technologies. The course also covers the importance of transconductance in defining amplifier performance, the non-idealities of mosfet, and the role of capacitance in mosfet. It explores the intricate aspects of transistor design and analysis, focusing on active devices and their applications in Radio Frequency (RF). The course concludes with a detailed comparison of BJT and MOSFET in terms of gain, transconductance, and power consumption.This course has been developed by Prof. Darshak Bhatt from IIT Roorkee for NPTEL.
