9 Difference Between Clipper And Clamper

What Is A Clipper?

The protection of the electronic devices is achieved through the use of clipper circuits. Clipper circuits are circuits that clip off or remove a portion of an input signal, without causing any distortion to the remaining part of the waveform.  In other words, a clipper is a device that limits the positive amplitude or negative amplitude of an input AC signal.  In some conditions, a clipper removes a small portion of the positive half cycle or both positive and negative half cycles.  Depending on the orientation of the diode, either the positive or the negative half cycle is removed.

Clipper circuits can also be referred to as current delimiter, amplitude delimiter, voltage delimiter, slicers, amplitude selectors or simply limiter. A clipper consists of both linear and non-linear elements but does not contain energy storing elements such as capacitor. The linear elements used in the clippers include resistors and the non-linear elements used in the clippers include diodes and transistors.

Types of Clippers

Types of clippers include:

  • Dual (combination) clipper.
  • Shunt negative clipper with bias.
  • Shunt negative clipper
  • Shunt positive clipper
  • Shunt positive clipper with bias
  • Series negative clipper with bias
  • Series negative clipper

What You Need To Know About Clipper

  1. Diode clipper is a wave shaping circuit which clips or cuts off the input waveform.
  2. Clipper can also be referred to as current delimiter, amplitude delimiter, voltage delimiter or simply limiter.
  3. In the clipper circuit, the DC level will remain the same.
  4. Clippers are used when we want to modify the amplitude voltage. For example, if we want to generate a square wave from a sinusoidal signal, we can use the clipper circuit.
  5. Positive clipper will clip positive portion of output waveform whereas negative clipper will clip negative portion.
  6. Shape of the output waveform can be Sinusoidal, square, rectangular etc.
  7. Clipper requires only DC battery and diode.
  8. Clipper is used in Transient protection circuit, waveform changing circuits, in noise limiter, Receivers and transmitters.
  9. Output voltage obtained from clipper circuit is less than the input voltage.

What Is A Diode Clamper?

A clamper is an electronic circuit that changes the DC level of a signal to the desired level without changing the shape of the applied signal. In other words, the clamper circuit moves the whole signal up or down to set either the positive peak or negative peak of the signal at the desired level. The clamper can also be referred to as a DC restorer, clamped capacitors, voltage multiplier or AC signal shifter.

A typical clamper is made up of a capacitor, diode and resistor. Some clampers contain an extra element referred to as DC battery. The resistors and capacitors are used in the clamper circuit to maintain an altered DC level at the clamper output.

 In a clamper circuit, the DC component is simply added to the input signal or subtracted from the input signal. A clamper circuit adds the positive DC component to the input signal to push it to the positive side. Similarly, a clamper circuit adds the negative DC component to the input signal to push it to the negative side.

Types Of Clamper Circuits

  • Positive clampers
  • Negative clampers
  • Biased clampers

What You Need To Know About Clamper

  1. Diode Clamper changes the DC reference of waveform. It shifts the DC level in upward or downward direction.
  2. Clamper can also be referred to as voltage multiplier or AC signal shifter.
  3. In the clamper circuit, DC level get shifted.
  4. Clamper is used when we require multiples of the input voltage at the output. For example, the clamper circuit is often utilized in the voltage multiple circuit.
  5. Positive clamper will shift output waveform in upward direction whereas negative clamper will shift output waveform in downward direction.
  6. The shape of the output waveform remains same as input waveform.
  7. Clamper requires battery, diode and capacitor.
  8. Clamper is used in test equipment, Sonars, Radars, Voltage multipliers, removing distortions in TV.
  9. Output voltage is more (multiples) of the input voltage.
