______________ is the point where collector current no longer increases for an increase in base bias.
Acts like a/an __________. - CORRECT ANS ***Saturation, short
A Common Base has a gain of how much? - CORRECT ANS ***10 (no phase inversion)
A Common Collector has a gain of how much? - CORRECT ANS ***1 (no phase inversion)
A Common Emitter has a gain of how much? - CORRECT ANS ***10
A small input controls a__________. - CORRECT ANS ***Large output
A transistor in a Common Emitter transfers an internal resistance from a low resistance in emitter base
to? - CORRECT ANS ***High resistance in collector base.
A transistor's stability and predictability are lost when the transistor has____________? - CORRECT ANS
***High gain.
Clipping occurs in an RC coupled amplifier when the______________. - CORRECT ANS ***Input
amplitude drives a transistor into cutoff or saturation.
Common Emitter Amplifier has high power gain because it: - CORRECT ANS ***Has medium voltage and
current gain.
Direct coupling doesn't use_________. - CORRECT ANS ***Reactive components.
How do transistor amplifiers operate? - CORRECT ANS ***By an AC input signal changing base bias.
, How does a Common Emitter affect the phase of an input signal? - CORRECT ANS ***It inverts the input
180° (flip)
How does Eb (Base voltage) determine the class of amplifier? - CORRECT ANS ***Class A Eb > .6
Class B Eb = .6
Class C Eb < .6
How is AvT (Total voltage gain) calculated in a Cascade Amplifier? - CORRECT ANS ***The product of
individual stage gains (Q1xQ2xQ3x...=AvT)
Ie (Emitter current) = ? - CORRECT ANS ***Ib (base current) + Ic (collector current)
In a Common Emitter, how does an open capacitor affect Base Bias? - CORRECT ANS ***It doesn't.
In a Common Emitter, if base voltage (base bias) increases, emitter current does what? - CORRECT ANS
***Increases.
Increasing collector voltage has how much affect on collector current? - CORRECT ANS ***Very little.
Is a value of 1100 acceptable in a three stage Cascade Amplifier (assumed value)? - CORRECT ANS
***Yes. There is an assumed error margin of ±10%. 1100 falls within the assumed value of 1,000's
margin.
Limiting action happens in series when a diode is________ and in parallel when a diode is________. -
CORRECT ANS ***Reverse biased, forward biased.
Properties of a Class A? - CORRECT ANS ***High fidelity, low efficiency, DC bias point within cutoff and
saturation limit.
Properties of Class B? - CORRECT ANS ***Medium fidelity, medium efficiency, DC bias point at cutoff.
Biased so collector current is 0 for half of input signal.
