Microelectronics: Devices To Circuits

Indian Institute of Technology Roorkee and NPTEL via Swayam


This course is intended for the core courses in Electronics Circuits taught to undergraduates in Electrical and Computer Engineering. The objective of this course is to develop the ability to analyse and design electronic circuits both analog and digital, discrete and integrated. The course starts with the basics of the device most seldom encountered in mixed designs and then go on to do circuit analysis in the later parts. INTENDED AUDIENCE: Any Interested Learners PREREQUISITES: First course on linear circuit analysis, A basic course on Semiconductor Devices and Digital Electronics. A course on Computer Organization will be also helpful (though not strictly required) INDUSTRY SUPPORT: Cadence; Synopsys; ST Microelectronics; NXP Semiconductors; Semiconductor Complex Limited, Chandigarh; Design House in general
