Choose the wrong statement:BJT is worked as an amplifier only in active regionVoltage divider bias circuit is most stable biasing circuitNegative feedback is required to design an oscillator circuitVoltage gain of BJT amplifier is almost constant at mid-band frequency

A BJT is said to be operating in the saturation region ifBase-emitter junction is reverse biased and base-collector junction is forward biasedBoth the junctions are reverse biasedBoth the junctions are forward biasedBase-emitter junction is forward biased and base-collector junction is reverse biased

An npn bipolar junction transistor (BJT) is operating in the active region. If the reverse bias across the base-collector junction is increased, thenThe effective base-width increases and common-emitter current gain decreasesThe effective base-width increases and common-emitter current gain increases The effective base-width decreases and common-emitter current gain decreasesThe effective base-width decreases and common-emitter current gain increases

A second condition for oscillation is  1 pointno gain around the feedback loopa gain of 1 around the feedback loopthe attenuation of the feedback circuit must be one-thirdthe feedback circuit must be capacitive

A BJT is said to be operating in the saturation region if

If the Wein Bridge Oscillator based on op-amp is tuned at 1KHz, what is the gain of feedback network? a. 2 b. 1/3 c. 3 d. 1/2
