The basic operation of a diode clipping circuits is such that, in forward biased condition, the diode allows current to pass through it, clamping the voltage. 2. Ask your students whether they would classify this circuit as a series or a shunt clipper. Clipper and clamper common in the electronics circuit is a topic. When a small portion of the negative half cycle is to be removed, it is called a biased negative clipper. therefore there are two cases: no current flows and V o u t is zero. When a small portion of the negative half cycle is to be removed, it is called a biased negative clipper. A typical clamper circuit consists of a capacitor, a diode, and a resistor. But in reverse biased condition, no any current flows through the diode, and thus voltage remains unaffected across its terminals. Depending on the direction of the diode and the polarity of the battery, the circuit will either clip the input waveform above or below the reference level. And simply it will act as a short circuit.
