Clamping using PN junction diodeΒΆ

A DC can be added to an AC signal using a diode.

Objective

Demostrate 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.
