A clipper circuit is an electronic circuit that limits or clips the voltage level of a waveform.
There are two types of clipper circuits: positive clipper and negative clipper.
Positive clipper circuit limits the positive half of the input waveform.
Negative clipper circuit limits the negative half of the input waveform.
Diodes are commonly used in clipper circuits to perform the clipping operation.
Examples of clipper circ...
A clamper circuit is used to shift the DC level of a signal without changing its shape.
Positive Clamper: shifts the DC level of the input signal to a higher level
Negative Clamper: shifts the DC level of the input signal to a lower level
Biased Clamper: shifts the DC level of the input signal to a desired level using a biasing voltage
Diode Clamper: uses diodes to clamp the input signal to a specific DC level
Clipper with the help of opamp is a technique used to limit the output voltage of a signal.
Clipper circuit is used to limit the voltage level of a signal by clipping off the peaks.
Opamp (operational amplifier) is a high-gain electronic amplifier used to amplify and manipulate signals.
By combining a clipper circuit with an opamp, the opamp can be used to control the clipping level and shape the output signal.
The opamp c...
A clamper circuit is used to shift the DC level of a signal.
A clamper circuit consists of a diode and a capacitor.
It is used to add or subtract a DC voltage to a signal.
The transistor can be used in a clamper circuit to control the clamping voltage.
The transistor acts as a switch to control the charging and discharging of the capacitor.
Example: A clamper circuit with a transistor can be used to shift the DC level of an...
I was interviewed in Dec 2024.
I applied via Campus Placement and was interviewed in Nov 2024. There was 1 interview round.
NAND gate can be implemented using a 2:1 multiplexer by connecting one input to select line and the other input to one of the data inputs.
Connect one input of the NAND gate to the select line of the 2:1 mux.
Connect the other input of the NAND gate to one of the data inputs of the 2:1 mux.
Connect the other data input of the 2:1 mux to ground.
The output of the 2:1 mux will be the output of the NAND gate.
A 4:1 mux can be implemented using two 2:1 muxes by selecting one of the 2:1 muxes based on the select line.
Use one 2:1 mux to select between the two inputs of the second 2:1 mux based on the select line
Connect the outputs of the two 2:1 muxes to get the final 4:1 mux output
A 58:1 mux can be implemented using 2:1 mux by cascading multiple levels of muxes.
Implement a 2:1 mux using 2 input lines and 1 output line.
Cascading multiple levels of 2:1 muxes can create a 4:1, 8:1, 16:1, and finally a 58:1 mux.
In this case, you would need 6 levels of 2:1 muxes to create a 58:1 mux.

Current flow in transistors is controlled by the voltage applied to the base terminal.
Transistors are three-terminal devices: emitter, base, and collector.
Current flows from the collector to the emitter when a voltage is applied to the base.
The amount of current flowing through the transistor is determined by the base current.
Transistors can be used as amplifiers or switches in electronic circuits.

This round is classified as easy to medium.
Current flows in a semiconductor due to the movement of charge carriers, either electrons or holes.
Current flows in a semiconductor when charge carriers (electrons or holes) move under the influence of an applied electric field.
In an n-type semiconductor, current is carried by electrons, while in a p-type semiconductor, current is carried by holes.
The flow of current can be controlled by applying a voltage across the s...
