Bipolar Junction Transistor (BJT)

DC bias establishes the dc operating point for an amplifier.

• True

• False

The dc load line intersects the horizontal axis of a transistor characteristic curve at VCE = VCC.

• False

• True

Voltage-divider bias is rarely used.

• True

• False

A pnp transistor requires bias voltage polarities opposite to an npn transistor.

• True

• False

A pnp transistor requires bias voltage polarities opposite to an npn transistor.

• Fixed bias

• Voltage-divider bias

• Self bias

• Common-Base bias

A small-signal amplifier_____________

• always has an output signal in the mV range

• goes into saturation once on each input cycle

• uses only a small portion of its load line

• is always a common-emitter amplifier

The disadvantage of base bias is that _________

• it is very complex

• it is too beta dependent

• it produces low gain

• it produces high leakage current

A bipolar junction transistor has three terminals.

• False

• True

These are the three regions of a BJT except ________

• base

• emitter

• collector

• gate

For operation in the linear or active region, the base-emitter junction of a transistor is forward biased.

• False

• True
