What is a common source of voltage?
Remember that voltage can exist without current. A battery is the most common voltage source for a circuit with the voltage that appears across the positive and negative terminals of the source being called the terminal voltage.
Is JFET a voltage source?
FET Constant Current Source Summary Remembering that the JFET is a voltage-controlled device, not a current-controlled device like the bipolar junction transistor.
What is the input resistance of a common gate amplifier?
Common gate amplifier characteristics summary

What is JFET used for?
The junction gate field-effect transistor ( JFET or JUGFET) is one of the simplest types of field-effect transistor. JFETs are three-terminal semiconductor devices that can be used as electronically -controlled switches, amplifiers, or voltage-controlled resistors.
How does a JFET work?
Describe how it works. A JFET consists of a channel and a pn junction. The gate controls the depletion width of the pn junction and with that the conductance of the channel. The most common JFET is depletion type. Depletion means that you have to apply a voltage between gate and source to close the channel.
What is common base amplifier?
Common base. In electronics, a common-base amplifier is one of three basic single-stage bipolar junction transistor amplifier topologies, typically used as a current buffer or voltage amplifier.
What are the different types of op amps?
Top 10 Fundamental Op Amp Circuits Voltage Follower. The most basic circuit is the voltage buffer, as it does not require any external components. Inverting Op Amp. In this configuration, the output is fed back to the negative or inverting input through a resistor (R2). Non-inverting Op Amp. Non-inverting Summing Amplifier. Inverting Summing Amplifier. Differential Amplifier. Integrator.
