Schematic and PCB layout design of Clipper and Clamper circuit using EasyEDA
Aim:
Schematic and PCB layout design of Clipper and Clamper circuit using EasyEDA
Components Requirement:
Hardware component:
Desktop/ Laptop Software
Tools: EasyEDA software
(For simulation)
Theory:
Circuits like RC, RL, RLC, clipper and clamper will fall under Wave shaping circuits.
Clipper:
Clipper is a circuit that is used to clip off (remove) a certain portion of the input signal
to obtain a desired output wave shape. Clipper circuits are referred to as voltage or current
limiters, amplitude selectors or slicers. Clipping circuit employs the component diode, resistor
and DC source. Resistor (R) is used to limit the current flowing through the diode under
forward biased condition. Clippers are broadly classified as positive clipper, negative clipper,
biased clipper and combinational clipper.
The diode conducts as long as the input voltage is greater than VB and the output
remains at VB until the input voltage becomes less than VB. When the input voltage is less
than VB, the diode does not conduct and acts as an open switch. Hence all the input signal
having less than VB as well as negative half cycle of the input wave will appear at the output,
shown in fig. The clipping level can be shifted up or down by varying the bias voltage VB.
Clamper:
In clamper circuits, a predetermined dc level is added to the input voltage. In other
words, the output is clamped to a desired dc level. If the clamped dc level is positive, the
clamper is called a positive clamper. On the other hand, if the clamped dc level is negative, it
is called a negative clamper. The other equivalent terms for clamper are dc inserter or dc
restorer.
The working of clamper circuits depends on the variation in the time constant of the
capacitor. This variation is the outcome of changing the current path of the diode with the
