Diode Voltage Clamp Circuit. Clamper circuit operation analysis in the figure below the positive peak of v 1 is clamped to the 0 v 0 7 v clamp level. Clamping circuits cont 2 in solving this type of circuits we need to i determine the applied voltage that will forward bias the diode.
Actually the positive and negative peaks of the signals can be placed at desired levels using the clamping circuits. As the dc level gets shifted a clamper circuit is called as a level shifter. Zener voltage regulator circuit this is one of the two configurations of overvoltage protection circuits using zener diode.
When a positive clamper circuit is unbiased the clamping circuit will fix the voltage lower limit to 0v.
Clamper circuit operation analysis in the figure below the positive peak of v 1 is clamped to the 0 v 0 7 v clamp level. This circuit not only protects the load side circuit but also regulates the input supply voltage to maintain a steady voltage. Clamper circuits consist of energy storage elements like capacitors. The final effect of clamping circuits is that the capacitor keeps a charge almost equivalent to the extreme peak value of input signal minus voltage drop across diode.
