The clamper does not restrict the peak-to-peak excursion of the signal (clipping); it moves the whole signal up or down so as to place its peaks at the reference level. A diode clamp (a simple, common type) consists of a diode , which conducts electric current in only one direction and prevents the signal exceeding the reference value; and a ...
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.
Baker called the technique "back clamping", but the circuit is now called a Baker clamp. Many sources credit Baker's report for the two-diode clamp circuit. [ 3 ] [ 4 ] [ 5 ] Also in 1956, Baker described the circuit in a patent application; the 1961 issued patent US 3,010,031 [ 6 ] claims the use of the clamp in symmetrical flip-flop circuits.
Clipping is a form of distortion that limits a signal once it exceeds a threshold. Clipping may occur when a signal is recorded by a sensor that has constraints on the range of data it can measure, it can occur when a signal is digitized , or it can occur any other time an analog or digital signal is transformed, particularly in the presence of ...
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. This makes transient ...

The Villard circuit, conceived by Paul Ulrich Villard, [p 1] consists simply of a capacitor and a diode. While it has the great benefit of simplicity, its output has very poor ripple characteristics. Essentially, the circuit is a diode clamp circuit. The capacitor is charged on the negative half cycles to the peak AC voltage (V pk). The output ...
It is possible to modify a regular semiconductor diode like 1N4148 to give it a negative differential resistance by injection of calibrated current pulses ,the diode being reversely biased near its avalanche zone .After this treatment the diode associated with an L/C circuit can oscillate , the frequency set by the L/C circuit .The maximum ...
