2. Clamper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Clamper_(electronics)

   A clamper will bind the upper or lower extreme of a waveform to a fixed DC voltage level. These circuits are also known as DC voltage restorers. Clampers can be constructed in both positive and negative polarities. When unbiased, clamping circuits will fix the voltage lower limit (or upper limit, in the case of negative clampers) to 0 volts.

3. Clipper (electronics) - Wikipedia

   en.wikipedia.org/wiki/Clipper_(electronics)

   A clamper circuit is not a clipper, but the simple diode version has a similar topology to a clipper with the exception that the resistor is replaced with a capacitor. The clamper circuit fixes either the positive or negative peaks at a fixed voltage (determined by the biasing voltage) rather than clipping them off.

5. Constant-current diode - Wikipedia

   en.wikipedia.org/wiki/Constant-current_diode

   It is known as a current-limiting diode (CLD) or current-regulating diode (CRD). Internal structure. It consists of an n-channel JFET with the gate shorted to the source, which functions like a two-terminal current limiter (analogous to a voltage-limiting Zener diode). It allows a current through it to rise to a certain value, but not higher.

6. Limiter - Wikipedia

   en.wikipedia.org/wiki/Limiter

   Limiting can refer to a range of treatments designed to limit the maximum level of a signal. Treatments in order of decreasing severity range from clipping, in which a signal is passed through normally but sheared off when it would normally exceed a certain threshold; soft clipping which squashes peaks instead of shearing them; a hard limiter, a type of variable-gain audio level compression ...

7. Snubber - Wikipedia

   en.wikipedia.org/wiki/Snubber

   The coil diode clamp makes the relay turn off slower ( = /) and thus increases contact arc [clarification needed] if with a motor load which also needs a snubber. The diode clamp works well for coasting a uni-directional motor to a stop, but for bi-directional motors, a bipolar TVS is used.
