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. These circuits clamp a peak of a waveform to a specific DC level compared with a capacitively coupled signal, which swings about its average DC level.
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.
English: Drawing of a Positive Biased Voltage Clamping Circuit together with simulated input and output graphs. Simulation was done in LTSpice, drawing with circuitikz and pgfplots, conversion to svg with Inkscape.
Positive Biased Voltage Clamping Circuit Source I (Jack1993jack ) created this work entirely by myself. Date 23:38, 13 January 2010 (UTC) Author ...
Asynchronous circuits and theory surrounding is a part of several steps in integrated circuit design, a field of digital electronics engineering. Asynchronous circuits are contrasted with synchronous circuits, in which changes to the signal values in the circuit are triggered by repetitive pulses called a clock signal. Most digital devices ...
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 clamper does not restrict the peak-to-peak excursion of the signal, it moves the whole signal up or down so as ...
Voltage and current errors: SEV-c circuitry does not actually measure the voltage of the cell being clamped (as does a two-electrode clamp). The patch-clamp amplifier is like a two-electrode clamp, except the voltage measuring and current passing circuits are connected (in the two-electrode clamp, they are connected through the cell). The ...
A rectifier circuit that converts both positive and negative parts of the input alternating current waveform into a unidirectional, direct current. fuse A circuit protective device that interrupts excessive current by melting a metal strip. fuzzy control A control system that relies on fuzzy logic instead of binary true/false conditions.
