ECE 4220 Analog Integrated Circuit Design (3C)
Integrated circuit design in silicon bipolar, MOS, and BiCMOS technologies for communications, sensor, instrumentation, data conversion, and power managment applications. Models for integrated circuit active devices in bipolar and MOS technologies; noise; current mirrors, active loads and references; amplifiers and output stages; operational amplifiers; and an introduction to data conversion circuits. Circuit design at the IC level; modern VLSI CAD software.
Analog signals are ubiquitous throughout the physical world. Analog circuits are therefore required to detect, amplify, manipulate, and process such signals. For example, analog circuits are required to interface with sensors/transducers [including microelectromechanical (MEMS) devices], converting physical responses, such as temperature, airflow, vibration, acceleration, stress, into electrical signals, amplifying these signals, and finally digitizing and communicating the resulting information to the electronic world. Analog circuits are required in the low-frequency/baseband sections of wireline and wireless communications transceivers. Analog circuits also form the core of many power management and control systems. Such analog circuits are now overwhelmingly realized as large-scale and very-large-scale integrated circuits, and these integrated circuits increasingly contain both analog and digital functions (i.e. mixed-signal) rapidly approaching system-on-a-chip implementations.
Typically offered: Fall. Program Area: Electronics.
Prerequisites: C- or better in 3204.
This course requires ECE 3204 as a prerequisite. This course builds on knowledge of amplifier analysis, feedback, transistor small signal models, frequency response, and operational amplifiers gained from successful completion of ECE 3204.
