In a class B push-pull amplifier, the transistors are biased slightly above cutoff to avoid
Often a common-collector will be the last stage before the load; the main function of this stage is to
The primary function of the bias circuit is to
The depletion-mode MOSFET
In order for feedback oscillators to have any practical value, the gain has to be
To get a negative gate-source voltage in a self-biased JFET circuit, you must use a
A JFET
Three different points are shown on a dc load line. The upper point represents the
Which of the following conditions are needed to properly bias an npn transistor amplifier?
The capacitor that produces an ac ground is called a(n)
The formula used to calculate the approximate ac resistance of the base-emitter diode (re) is
A certain amplifier has a voltage gain ofThat gain expressed in decibels is 46.4 dB.
The voltage measured from the collector to the emitter is the sum of the voltage base-emitter plus the voltage collector-base.
A decrease in base current of a CE amplifier causes the voltage measured between the emitter and the collector to increase.
In an n-type JFET, current will flow when a positive voltage is applied to the drain and a negative voltage is applied to the source.
If the drain, source, and channel of a MOSFET are all a p-type material, and it operates in both modes, this is an n-channel D-MOSFET.
A practical CE amplifier has the input on the base and the output taken off the emitter.
An essential requirement of a feedback oscillator is a phase shift around the feedback loop of 360°.
