In the common-emitter circuit with a fixed bias, the most often used mothed to regulate the base current is to regulate ( )
举一反三
- In the fixed bias circuit, the Q-point current and voltage are a function of ( ), since ( ) is temperature sensitive, Q-point is ( )
- β is the ratio of _____. A: collector current to emitter current B: base current to collector current C: collector current to base current D: emitter current to collector current
- When a BJT is operating in the active region, the voltage drop from the base to the emitter VBE is approximately equal to the____ A: base bias voltage B: base current times the base resistor C: diode drop (about 0.7 V) D: emitter voltage
- Which transistor amplifier configuration is the most commonly used? A: common-emitter B: common-collector C: common-base D: None of these are used more often than the others.
- 2. The word “regulate” most nearly means______.
