Semiconductor Fundamentals Unit 4 – Diode Wave Shaping and Zener Regulation
UNIT 4 – DIODE WAVE SHAPING AND ZENER REGULATION
UNIT OBJECTIVE
At the completion of this unit, you will be able to demonstrate wave shaping, zener diode
operation, and zener diode voltage regulation by using diode circuits.
UNIT FUNDAMENTALS
Diode circuits can be configured to output a waveform with a different shape than the input
waveform.
A limiter (or clipper) circuit removes all or part of the input alternation, as shown.
A clamper circuit shifts the positive or negative amplitude extreme of an input waveform to a
different dc output voltage reference level, as shown.
