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.

More formally, for every two positive integers p and q, a (p:q)-positional game is a game in which the first player picks p elements per turn and the second player picks q elements per turn. The main question of interest regarding biased positional games is what is their threshold bias - what is the bias in which the winning-power switches from ...
I verified the equations with PSpice. The equations used is this article are completely off. I don't understand where the 2 multiplier comes from. Likewise, the equations for the unbiased circuits has the same problem. Vbias clearly drops off but the equations should be V in-V D for the positive clamper and -V in +V D for the negative clamper ...
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 voltage clamp operates by negative feedback.The membrane potential amplifier measures membrane voltage and sends output to the feedback amplifier; this subtracts the membrane voltage from the command voltage, which it receives from the signal generator.
The reactances of synchronous machines comprise a set of characteristic constants used in the theory of synchronous machines. [1] Technically, these constants are specified in units of the electrical reactance (), although they are typically expressed in the per-unit system and thus dimensionless.
Therefore, leakage from the terminal determines the maximum voltage attainable. In the Van de Graaff generator, the belt allows the transport of charge into the interior of a large hollow spherical electrode. This is the ideal shape to minimize leakage and corona discharge, so the Van de Graaff generator can produce the greatest voltage.
