Analog Circuit Design Courses by Kent Lundberg

Feedback Circuit Techniques

All electronic systems employ feedback. All analog circuits, including op amps, oscillators, filters, and power supplies (just to name a few), critically depend on feedback. Some of these feedback loops are explicit, some are implicit, some are intentional, and some are unintentional. In all cases, the analysis and design of circuits using feedback requires the knowledge of analytical techniques, creative design, and an appreciation for possible trade-offs. Understanding feedback theory, and its use in practical applications, is the key to successful system design.

Circuits discussed include passive networks, op-amp filters, state-variable types, impedance converters, switched capacitors, and operational transconductance amplifiers. The second section of the course covers analog oscillator analysis and design, including feedback and nonlinear-circuit analysis, amplitude stabilization, voltage control, and a variety of applications.

Feedback Control Systems

Systems that employ feedback control are all around you: stereo amplifiers, hard-disk drives, automobiles, radar antennas, and high-performance airplanes, to name a few. The creation of successful control systems almost always requires more than the application of a set of analytical techniques. Good feedback-system design requires the connection and application of theory to problems of practical interest, as well as a rich understanding of how to make trade-offs amongst all the parts of a system.

This course covers the design of feedback systems, using the intuitive analysis tools of classical control theory. The course content includes time-domain, frequency-domain, and s-plane concepts that provide insight into the behavior of linear and nonlinear systems. Applications to the design of mechanical and electronic systems, including servomechanism design, vibration isolation, operational-amplifier compensation, power conversion, waveform generation, and phase-lock loops are explored.
