Clipper (electronics), a circuit that imposes a fixed limit and does not offset the signal; Envelope detector, a circuit that outputs the maximum (or minimum); a clamper with the diode and capacitor exchanged; Schottky diode; Snubber, a circuit that reduces dV/dt or limits peak voltage, in order to reduce arcing or breakdown
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.
A circuit designer may intentionally use a clipper or clamper to keep a signal within a desired range. When an amplifier is pushed to create a signal with more power than it can support, it will amplify the signal only up to its maximum capacity, at which point the signal will be amplified no further.
The base diode allows a Si diode clamp to be used with a Si transistor and keeps V CE around a diode drop and much greater than V CE(sat). Unfortunately, it turns off and creates a high-impedance return path when trying to turn the transistor off. Although the base charge has been minimized, it is now more difficult to draw charge out of the base.

A transient-voltage-suppression diode can respond to over-voltages faster than other common over-voltage protection components such as varistors or gas discharge tubes. The actual clamping occurs in roughly one picosecond , but in a practical circuit the inductance of the wires leading to the device imposes a higher limit.
Various semiconductor diodes. Left: A four-diode bridge rectifier.Next to it is a 1N4148 signal diode.On the far right is a Zener diode.In most diodes, a white or black painted band identifies the cathode into which electrons will flow when the diode is conducting.
The diode would be in parallel with the series inductor and load. The same way by equating the average inductor current during the turn-on and turn-off time, we can get the average voltage by [ 6 ] V a v e = α V s {\displaystyle V_{ave}=\alpha V_{s}}
