Exam 31: Transistor Amplifiers

One way to significantly reduce distortion in a CE amplifier is to add a(n)

When the emitter follower is used to isolate a low value of load resistance from the high impedance collector, the emitter follower serves as a(n)

The output impedance of an emitter follower is usually

The phase shift between v_in and v_out for a common-emitter amplifier is

Which transistor configuration provides some desirable features for operation at higher frequencies?

When analyzing a common-emitter amplifier, it is common practice to represent the emitter diode as a small resistance.

The main purpose of the emitter follower is to ______________ the relatively low value of load resistance from the high impedance collector.

The input impedance of an amplifier is the input impedance seen by the ac source driving the amplifier.

Which transistor configuration provides current and power gain, but provides a voltage gain of approximately one?

The purpose of the dc bias is to

Which transistor amplifier configuration offers effective impedance matching?

One way to significantly reduce the variations in the CE A_V caused by changes in equivalent ac resistance is to add a(n)

The ratio of ac collector current to ac base current is called the dc beta.

The common-collector amplifier is used to provide current gain and power gain.

The purpose of the dc bias is to establish the desired Q point.

The common-collector amplifier is usually referred to as a

What is the input-output phase relationship of the common-base configuration?

Because the output signal follows the input signal, the common-collector amplifier is usually referred to as a(n) ______________ follower.

The common-emitter amplifier is the only transistor amplifier configuration that produces a 180° phase shift between v_in and v_out.

The emitter follower has a high input impedance and a low output impedance which makes it ideal for impedance ______________ applications.
