BJT Amplifier Quiz

In a BJT amplifier, the mid-band voltage gain is primarily determined by:

• Coupling capacitors

• Bypass capacitor

• Transistor parameters and resistors

• Power supply voltage

The gain of a common-emitter BJT amplifier decreases at high frequencies mainly due to:

• Emitter resistance

• Base current

• Junction capacitances

• Load resistance

What is the typical unit for the gain of a BJT amplifier expressed in decibels?

• Volts

• Amperes

• dB

• Ohms

The lower cutoff frequency in a BJT amplifier is influenced by:

• Collector resistance

• Coupling and bypass capacitors

• Thermal voltage

• Supply voltage

The frequency range where the BJT amplifier provides consistent gain is known as:

• Saturation region

• Cutoff region

• Transition band

• Midband
