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. [ 2 ]
A simple diode clipper can be made with a diode and a resistor. This will remove either the positive, or the negative half of the waveform depending on the direction the diode is connected. The simple circuit clips at zero voltage (or to be more precise, at the small forward voltage of the forward biased diode) but the clipping voltage can be ...
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.
While standard silicon diodes have a forward voltage drop of about 0.7 V and germanium diodes 0.3 V, Schottky diodes' voltage drop at forward biases of around 1 mA is in the range of 0.15 V to 0.46 V (see the 1N5817 [6] and 1N5711 [7]), which makes them useful in voltage clamping applications and prevention of transistor saturation.
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 ...

In these applications, stabistors offer improved dynamic impedance (voltage change vs. current) than low voltage zener diodes where tunneling instead of avalanche current is dominant. [1] [2] Other typical applications include bias stabilization in class-AB output stages, clipping, clamping, meter protection, etc. [3]
