The negative swing of the output will not dip below about −0.6 V, assuming a silicon PN diode. [1] A clamper (or clamping circuit or clamp) is an electronic circuit that fixes either the positive or the negative peak excursions of a signal to a defined voltage by adding a variable positive or negative DC voltage to it.

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.
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 ...
This simple diode clamp will clamp the negative peaks of the incoming waveform to the common rail voltage. A diode clamp circuit can take a periodic alternating current signal that oscillates between positive and negative values, and vertically displace it such that either the positive or the negative peaks occur at a prescribed level. The ...
A common example of an "active resistance" circuit is the negative impedance converter (NIC) [45] [46] [115] [125] shown in the diagram. The two resistors R 1 {\displaystyle R_{\text{1}}} and the op amp constitute a negative feedback non-inverting amplifier with gain of 2. [ 115 ]
