By applying voltage to G, one can control ID. Most FETs have a fourth terminal called the body, base, bulk, or substrate. This fourth terminal serves to bias the transistor into operation; it is rare to make non-trivial use of the body terminal in circuit designs, but its presence is important when setting up the physical layout of an integrated circuit. The size of the gate, length L in the diagram, is the distance between source and drain.

The width is the extension of the transistor, in the direction perpendicular to the cross section in the diagram i. Typically the width is much larger than the length of the gate.

The names of the terminals refer to their functions. The gate terminal may be thought of as controlling the opening and closing of a physical gate.

This gate permits electrons to flow through or blocks their passage by creating or eliminating a channel between the source and drain. Electron-flow from the source terminal towards the drain terminal is influenced by an applied voltage. The body simply refers to the bulk of the semiconductor in which the gate, source and drain lie.

Usually the body terminal is connected to the highest or lowest voltage within the circuit, depending on the type of the FET. The body terminal and the source terminal are sometimes connected together since the source is often connected to the highest or lowest voltage within the circuit, although there are several uses of FETs which do not have such a configuration, such as transmission gates and cascode circuits.

Note that the threshold voltage for this device lies around 0. FET conventional symbol types The FET controls the flow of electrons or electron holes from the source to drain by affecting the size and shape of a "conductive channel" created and influenced by voltage or lack of voltage applied across the gate and source terminals.

For simplicity, this discussion assumes that the body and source are connected. This conductive channel is the "stream" through which electrons flow from source to drain. If the active region expands to completely close the channel, the resistance of the channel from source to drain becomes large, and the FET is effectively turned off like a switch see right figure, when there is very small current.

This is called "pinch-off", and the voltage at which it occurs is called the "pinch-off voltage". Conversely, a positive gate-to-source voltage increases the channel size and allows electrons to flow easily see right figure, when there is a conduction channel and current is large.

In an n-channel "enhancement-mode" device, a conductive channel does not exist naturally within the transistor, and a positive gate-to-source voltage is necessary to create one. The positive voltage attracts free-floating electrons within the body towards the gate, forming a conductive channel. But first, enough electrons must be attracted near the gate to counter the dopant ions added to the body of the FET; this forms a region with no mobile carriers called a depletion region , and the voltage at which this occurs is referred to as the threshold voltage of the FET.

The average current in each supply is measured to be 20 mA.

Find the voltage gain, current gain, and power gain expressed as ratios and in decibels as well as the supply power, amplifier dissipation, and amplifier efficiency. What voltage and power gains expressed in dB would you expect with the load connected? If the amplifier has a peak output-current limitation of 20 mA, what is the rms value of the largest sine-wave input for which an undistorted output is possible?

What is the corresponding output power available? What overall voltage gain results as measured from the source internal voltage to the load?

Where did all the gain go? What would the gain be if the source was connected directly to the load? What is the ratio of these two gains? This ratio is a useful measure of the benefit the amplifier brings. Compare this value with the result in Example 1.

The signal source provides a mV rms signal and has a resistance of 0.

Your design should utilize the minimum number of stages and should ensure that the signal level is not reduced below 10 mV at any point in the amplifier chain.

Choose an arrangement that would cause minimum disruption to an operating circuit. Hint: Use parallel rather than series connections. Your problem is to decide how the amplifiers should be connected.Notify me of new posts by email. The FET is said to be in saturation mode; [11] although some authors refer to it as active mode, for a better analogy with bipolar transistor operating regions.

Even though the conductive channel formed by gate-to-source voltage no longer connects source to drain during saturation mode, carriers are not blocked from flowing.
