A clipper circuit is a wave-shaping tool that uses diodes to modify waveforms. These circuits are common in TVs, radar transmitters, and receivers. Consider a dual-clipper circuit consisting of two ideal diodes, each connected to a biasing battery, and a resistor. During the positive half-cycle of the input AC signal, diode D1 is forward-biased by the input signal and reverse-biased by the biasing battery. In contrast, diode D2 is reverse-biased by both. If the input voltage is less than the biasing voltage, diode D1 acts as an open switch, resulting in the output reflecting the same applied voltage. However, when the input voltage exceeds the biasing voltage, diode D1 becomes forward-biased, blocking the input voltage and leaving no signal at the output. For the negative half-cycle, a similar process occurs with diode D2 clipping the signal and the output voltage being limited by D2's biasing voltage. The resistance value is meticulously selected to balance adequate forward diode current and minimal voltage drop from the reverse diode current.
