ENEE411 Analog and Digital Electronics II

Course Description: This course is the second in a series that provides students with a strong background in the design and analysis of mixed signal electronics. ENEE 419A is an elective that begins with a description of analog and digital device models for analysis, design and simulation of transistor level electronic circuits. The course mainly utilizes Metal Oxide Silicon Field Effect Transistors (MOSFETs), which are the most common devices in today’s integrated circuits (chips). The course reviews fundamental single transistor configurations. Multi-transistor circuits are discussed such as current mirrors, differential amplifiers, voltage references, operational amplifiers and data converters. Frequency response, feedback, and stability compensation in multi-transistor circuits are covered. Complementary Metal Oxide Silicon (CMOS) implementations of static and clocked digital as well as mixed signal circuits are discussed.
