Operational amplifier (op amp) theory and design of a very simple op amp using discrete components (transistors, resistors, capacitors). Including content on op amp stages (difference amplifier, gain stage, output stage), bandwidth, gainbandwidthproduct (GBP), op amp performance criteria, negative feedback, and more. Final demonstrations of realworld implementation on a PCB using the Digilent Analog Discovery Pro.
