Connection to Other Courses

E3 238: Analog VLSI Circuits

E3 237: ICs for Wireless Communication

E3 xxx: Phase Locked Loops and I/Os

E3 yyy: Data Conversion Systems

E8 242: RF ICs and Systems

• This course will be a prerequisite for three advanced VLSI courses on, ICs for Wireless Communication, Phase Locked Loops/IOs and Data Conversion Systems.

• It is recommended that students take the Digital VLSI Circuits course (Prof. Thakur) and the RF Systems Course (Prof. Vinoy) before signing up for the relevant advanced courses.

E3 284: Digital VLSI Circuits

Why Analog ?

• Real-world signals are analog: continuous in amplitude, and continuous in time.

• Modern signal processing has evolved to be digital or discrete-time. Most signal processing is performed in the digital domain.

• Most analog systems perform the sensing, amplification, transmission and reception of real-world signals, before they can be processed by

digital systems.
