Series clippers

The diode and output are connected in a series of clipper circuits. In these clippers, when the diode is forward biased and conducting, the input signal is visible at the output.

It is separated into clippers that are positive and negative.

Series Positive clippers: 

The positive half of the waveform is removed or clipped with a series of positive clippers. The diode is reverse-biased and connected in series with the output in a series positive clipper, as depicted in the figure below.

Vi is applied as the input signal, and the load resistor receives the output. The voltage at point A is higher than point B during the input’s positive half-cycle. As a result, there is no current conduction and the diode is in reverse bias. There is no voltage drop at the Rl because the input signal cannot pass. As a result, the output does not display the positive half cycle as it does in the figure.

The voltage at point A is lower than that at point B during the negative half-cycle, causing the diode to become forward-biased and the signal to pass through it. The signal is visible throughout the Rl. As a result, the negative half cycle appears at the output after passing through the circuit.
It shows how it clips the positive half of the input waveform and allows the negative half, as shown in the figure.

Series Positive Clippers with Bias: A portion of the half cycle, not the entire halve, is clipped by the biasing in the clippers circuit. To achieve the desired waveforms, a series of positive clippers with either positive or negative biasing is used.

Positive Bias: The positive of the battery is connected to the P side of the diode in a positive clipper circuit like the one below.

The diode is switched off because the voltage at point A is higher than that at point B during the positive half cycle. However, the positive of yet another voltage source is connected to the diode’s P side. The diode is biased forward by the voltage source or battery.
The diode continues to be in forward bias and conducts if the input voltage is lower than the battery voltage. As a result, the output displays the signal. The diode becomes reverse-biased and ceases to transmit the input signal when the input voltage exceeds the battery voltage. As a result, the output displays the battery voltage Vb.

The input and battery voltage causes the diode to be forward biased during the negative half cycle. Consequently, the output signal is produced after the input signal has passed through the diode.

Negative Bias: According to the diagram below, the battery in the negative biased series positive clipper is connected in reverse with the diode.

The negative battery and the input voltage cause the diode to be reversed biased during the positive half cycle. As a result, only the negative battery voltage is displayed at the output during the positive half cycle, when the diode does not conduct.
The diode becomes forward-biased during the negative half-cycle when the polarity of the input voltage is reversed. However, the negative battery causes the diode to be reverse-biased. In this way, the diode possibly becomes forward one-sided in the event that the information voltage increments over the battery voltage and the info signal show up at the result. Otherwise, the output displays a negative voltage from the battery.

Series Negative Clipper: 

The negative half of the input cycle is clipped by the series negative clipper circuit. Below is a diagram of its circuitry.

The input voltage causes the diode to be forward-biased during the positive half cycle. Subsequently, the info signal goes through the diode and shows up in the result.

The diode becomes reverse-biased and does not conduct during the negative half cycle. As a result, the negative half cycle of the input waveform is clipped, and there is no voltage at the output.

Series Negative Clippers with Bias: Instead of clipping the entire negative half, the waveform is modified by biassing the series negative clipper with either a positive or negative voltage battery.

Positive Bias: The voltage of the input signal causes the diode to be forward-biased during the positive half cycle. Nonetheless, the battery voltage causes it to be biased in the opposite direction. The diode’s state is influenced by both voltage sources. As a result, the diode will only conduct when the input voltage exceeds the battery voltage because it will be forward-biased.

The input voltage is initially lower than the battery voltage, causing the diode to be reverse biased and not conduct. As a result, the output shows the battery voltage. When the input signal rises above the battery voltage, as depicted in the figure, the input signal is visible at the output for that portion.

The battery voltage and the input voltage cause the diode to be reversed and biased during the negative half of the cycle. Consequently, during the entire negative half cycle, the output displays only battery voltage.

Negative Bias: The battery voltage and the input signal cause the diode to be forward-biased during the positive half cycle. As a result, the signal flows through the diode for the entire positive half cycle, resulting in the same output as the input.

The input voltage forces the diode into reverse bias during the negative half-cycle, but the battery voltage continues to forward bias the diode. Only when the battery voltage exceeds the input voltage does the diode conduct throughout the entire cycle.

The diode conducts when the input voltage is initially lower than the battery voltage, and the signal appears at the output. However, as depicted in the figure, when it exceeds the battery voltage, the diode blocks the input signal and the battery voltage begins to appear at the output.

A clipper in electronics is a circuit created to stop a signal from going over a specific reference voltage level. The remaining portion of the waveform that is applied is not distorted by a clipper. The clipping of a portion of a wave from an input signal is done with Clipper Circuits. A diode is the main component, and it can be used in series or parallel. Clippers have the benefit of removing the unwanted noise that is present in an AC signal’s amplitude.
