This is a series of lectures based on material presented in the Electronics I course at Vanderbilt University. This lecture includes: 00:00 Iterative analysis of circuits with forward-biased p-n (non-ideal) diodes 20:42 Simplified diode analysis using the constant voltage drop (CVD) model 29:56 The mistake of using a simulator to randomly choose component values in place of intelligently thinking about the design 31:15 A simple diode voltage reference 33:40 An example problem with two diodes 45:11 Small-signal analysis of diodes 54:09 The concept of "biasing" 1:00:44 Definition of the small-signal AC approximation 1:06:28 The methodology of small-signal circuit analysis in electronic design
