 Clipper and Clamper

What are Clippers: -

Clippers, additionally known as limiters, are electronic circuits used to cast off or "clip" a portion of the input signal without distorting the last part of the waveform. Clippers are frequently used in programs where the sign voltage is desired to be restrained to a favoured range.

Basic Concept:

Clipper circuits use diodes (occasionally in aggregate with resistors and voltage resources) to block parts of the input signal above or below a certain threshold.

Types of Clippers: -

Clippers are especially labelled into:



1. Series Clipper

In this circuit, the diode is connected in collection with the burden. It allows or blocks sign quantities relying on the direction of the diode.

  • Positive Series Clipper – Clips the high-quality half-cycle.
  • Negative Series Clipper – Clips the terrible 1/2-cycle.

2. Shunt Clipper (Parallel Clipper)

Here, the diode is connected in parallel to the weight. The circuit directs the unwanted portion of the enter signal far away from the weight.

  • Positive Shunt Clipper – Clips the high-quality cycle with the aid of directing it away via the diode.
  • Negative Shunt Clipper – Clips the negative half of the waveform.

3. Biased Clipper

This sort of clipper uses a voltage source similar to a diode to set the clipping level to a voltage aside from 0V.

  • Positive Biased Clipper – Clips the waveform above a particular fantastic voltage level.
  • Negative Biased Clipper – Clips underneath a certain bad voltage.

4. Dual (Combinational) Clipper

Clips both superb and terrible peak the use of two diodes and, once in a while, two voltage sources. This is used for shaping waveforms symmetrically.



Applications of Clippers: -

  • Voltage limiters in electricity substances
  • Waveform shaping in oscilloscopes and signal generators
  • Protecting circuits from voltage spikes
  • Removing noise or distortion beyond a certain threshold




What are Clampers: -

Clampers, additionally called DC restorers, are circuits that shift the entire voltage stage of a waveform up or down without changing the form of the waveform.

Basic Concept:

Clampers upload a DC stage to an AC signal. Unlike clippers, they do not cut any part of the waveform—they shift the entire waveform vertically.

Clampers use diodes, capacitors, and, from time to time, resistors.

Types of Clampers: -

1. Positive Clamper

Shifts the entire waveform upwards so that the terrible peaks are added to or above 0V.

2. Negative Clamper

Shifts the entire waveform downwards so that the high-quality peaks are introduced to or beneath 0V.

3. Biased Clamper

A biased clamper consists of a DC battery or voltage supply to manipulate the amount of shift.

  • Positive Biased Clamper – Adds more upward DC offset.
  • Negative Biased Clamper – Adds more downward DC offset.


Applications of Clampers: -

  • Restoring DC stages in television receivers
  • Signal processing in conversation systems
  • Waveform transformation
  • Generating reference voltages
  • Removing undesirable DC offsets in indicators



Real-Life Example: -

Clipper Example:

In audio systems, clippers are used to protect amplifiers by limiting input voltages to prevent distortion or damage.

Clamper Example:

In analogue TV, a clamper circuit restores the lost DC component of the video signal to ensure proper picture display.

Conclusion: -

Clippers and clampers are foundational circuits in electronics, playing a crucial function in shaping and conditioning alerts. While clippers eliminate unwanted quantities of signals, clampers shift them to favoured voltage ranges. Both use primary additives like diodes, resistors, and capacitors, but their packages span from TV receivers and audio systems to communication gadgets and business electronics.

Understanding the difference between clippers and clampers is essential for designing efficient analogue circuits, and getting to know them opens the door to superior signal processing and safety systems.
