AMITY SCHOOL OF ENGINEERING & TECHNOLOGY
B.Tech (ECE) Semester-IV
ANALOG ELECTRONICS II
Course Code: BTE 403 Credit Units: 04
Course Objective: The purpose of this course is to introduce the
student to the application of semiconductor devices in linear
analog circuits. To
insure the usefulness of the course material to both computer
engineers and electrical engineers, the course stresses circuit
designs using the operational amplifier.
