What does it mean to source current?
the source current is the current that flows from the power source.

What is the operation of FET?
A Field Effect Transistor is a device with a single channel (conductor between two of the terminals). This channel is turned on an off by a voltage applied to the third terminal which is connected to the conducting channel in a J fet (junction Fet) or isolated from the channel in a Metal Oxide Semiconductor (MOS) fet. To keep the explanation simple, an enhacement mode MOS FET pulls charge carriers (electrons for N channel and holes for P channel) into the channel so its resistance decreases. This turns it on. By removing this voltage, charge carries move out of the channel and the FET turns off. It can be turned on partially by putting a small voltage on the control terminal called the GATE. In an N channel FET, the charge carriers (electrons) move from the SOURCE terminal (-ve) to the DRAIN terminal (+ve) when the FET is on. The voltage on the GATE is applied with respect to the SOURCE. In a P channel enhancement mode FET, charge carriers (holes) are also pulled into the channel in the same way but because the charge carriers are holes, the SOURCE is the +ve terminal and the DRAIN is the negative. The holes referred to are gaps in the crystal lattice of a substance like silicon which is doped (impurities added) with aluminum which has only 3 electrons in the outer shell instead of 4 like silicon. In a depletion mode FET, everything is the same except in reverse. Charge carriers are pushed OUT of the conducting channel.
What is drain resistance?
drain resistane is basically the resistance offered by the drain terminal of the fet device.its the ratio of change in drain to source voltage to the change in drain current at a constant gate to source voltage.
Why FEt is source follower?
A Field Effect Transistor (FET) operates as a source follower due to its configuration where the output is taken from the source terminal. In this setup, the input signal is applied to the gate, and the output voltage at the source closely follows the gate voltage, minus a small threshold voltage drop. This characteristic allows the source follower to provide a high input impedance and low output impedance, making it an effective buffer for signal amplification without significant gain.
Source to drain in FET is made of which material?
Semiconductor.
Which mos needs logic '1' on its gate terminal to get ON?
It is NMOS FET. PMOS works in a reverse way.
What is Cut-off voltage in fet?
fet is a voltage controlled device...cut off voltage in fet refers to that voltage of the gate - source junction at which the current flow through channel is zero
Fet in cut off voltage?
fet is a voltage controlled device...cut off voltage in fet refers to that voltage of the gate - source junction at which the current flow through channel is zero
Why the name is FET?
FET stands for Field Effect Transistor. The name FET comes because the gate current of a field effect transistor is zero and current present in the source conductor is due to an electric field produced by the substrate material placed between the gate and the source.
What is a cs amplifier?
A common-source (CS) amplifier is a type of field-effect transistor (FET) amplifier configuration that provides voltage amplification. In this setup, the input signal is applied to the gate terminal of the FET, while the output is taken from the drain terminal. It is characterized by its high input impedance and moderate output impedance, making it suitable for interfacing with high-impedance sources. The CS amplifier is widely used in analog circuits due to its simplicity and effectiveness in amplifying signals.
