Diodes and rectification
The diode conducts past threshold; the rectifier clips or folds the sinusoid.
Key formulas
- Shockley equation
The Shockley curve I=Is(e^{v/(n VT)}−1) rises steeply in forward bias.
- Silicon diode threshold model
The ~0.7 V silicon threshold approximates the knee of the IV curve.
- Half-wave rectifier
The half-wave rectifier passes only the positive half-cycles.
- Full-wave rectifier
The full-wave rectifier folds both half-cycles to positive.
