Clamping using PN junction diode
A DC can be added to an AC signal using a diode.
Objective
Demonstrate clamping of an AC signal at different levels, using a PN junction diode
Procedure
- Make connections as shown in the figure.
- Set WG to 1000 Hz
- Load resistor may be omitted, if it distorts the output
- Change PV1 and note the difference in the output
Discussion
The clamping level is decided by the applied DC voltage and the diode
drop.
