2. CLIPPERS :
THE CLIPPING CIRCUITS USING DIODES HAVE THE ABILITY TO “CLIP” OFF OR REMOVE A PORTION OF THE INPUT SIGNAL WITHOUT DISTORTING THE REMAINING PART OF THE WAVEFORM.
TYPES :
SERIES CLIPPER
PARALLEL CLIPPER

3. SERIES CLIPPER : HERE THE DIODE IS CONNECTED IN SERIES WITH THE LOAD.
IN SERIES THERE ARE THREE TYPES :
SERIES POSITIVE CLIPPER :
THE DIODE FACING LEFT IN SERIES WITH THE LOAD IS POSITIVE ONE.
SERIES NEGATIVE CLIPPER:
THE DIODE FACING RIGHT IN SERIES WITH THE LOAD IS NEGATIVE ONE.

4. SERIES POSITIVE & NEGATIVE CLIPPER SHOWN BELOW :

5. SERIES BIASED CLIPPER :
HERE THE ADDITION OF A DC SUPPLY IN THE SERIES CLIPPER IS USED. THIS WILL HAVE A PRONOUNCED EFFECT ON THE OUTPUT OF THE CHOPPER
TYPES :
BIASED SERIES POSITIVE CLIPPER
BIASED SERIES NEGATIVE CLIPPER

6. SERIES BIASED POSITIVE & NEGATIVE CLIPPER SHOWN BELOW :

7. PARALLEL CLIPPER : HERE THE DIODE IS CONNECTED PARALLEL WITH THE LOAD.
IN PARALLEL THERE ARE THREE TYPES :
PARALLEL POSITIVE CLIPPER :
THE DIODE FACING DOWNWARD IN PARALLEL WITH THE LOAD IS POSITIVE ONE.
PARALLEL NEGATIVE CLIPPER:
THE DIODE FACING UPWARD IN PARALLEL WITH THE LOAD IS NEGATIVE ONE.

8. PARALLEL POSITIVE & NEGATIVE CLIPPER SHOWN BELOW :

9. PARALLEL BIASED CLIPPER :
HERE THE ADDITION OF A DC SUPPLY IN THE PARALLEL CLIPPER IS USED. THIS WILL HAVE A PRONOUNCED EFFECT ON THE OUTPUT OF THE CHOPPER.
TYPES :
BIASED PARALLEL POSITIVE CLIPPER
BIASED PARALLEL NEGATIVE CLIPPER

10. PARALLEL BIASED POSITIVE & NEGATIVE CLIPPER SHOWN BELOW :

11. APPLICATIONS : WAVESHAPPING CIRCUITS.
AS A DIODE CLAMP TO PROTECT SENSITIVE ELECTRONIC CIRCUITS.
AS A COMBINATIONAL CLIPPER.

12. CLAMPERS :
THE CLAMPER CIRCUITS ARE USED TO “CLAMP” THE INPUT SIGNAL TO A DIFFERENT DC LEVEL.
IN OTHER WORDS, CLAMPER ADDS A DC VOLTAGE TO THE SIGNAL.
TYPES :
POSITIVE CLAMPER
NEGATIVE CLAMPER

13. POSITIVE CLAMPER
A POSITIVE CLAMPER WILL ADD A POSITIVE DC LEVEL TO THE INPUT SIGNAL.
A POSITIVE CLAMPER IS SHOWN BELOW :

14. NEGATIVE CLAMPER
A NEGATIVE CLAMPER WILL ADD A NEGATIVE DC LEVEL TO THE INPUT SIGNAL.
A NEGATIVE CLAMPER IS SHOWN BELOW :

15. APPLICATIONS : IN THE VOLTAGE MULTIPLIERS.
IN ORDER TO PROVIDE DC SHIFT TO THE INPUT WAVEFORM.
