If a BJT is applied in the cutoff region, the base-emitter junction must be ( ) biased and the base-collector junction must be ( ) biased
举一反三
- When a BJT has its base-emitter junction reverse biased and its collector-base junction reverse biased, it is in the ( ).
- When a BJT is biased in the cutoff region the collector-to-emitter voltage is typically equal to ( ). A: the emitter voltage B: the collector supply voltage C: 0.03 V D: the collector current times the collector resistor
- 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
- The base substitution in the coding region of the gene must lead to the change of protein structure
