What will be the emitter current in a differential amplifier, where both the transistor are biased and matched? (Assume current to be IQ)
A. IE = IQ/2
B. IE = IQ
C. IE = (IQ)2/2
D. IE = (IQ)2
Answer:A
What will be the emitter current in a differential amplifier, where both the transistor are biased and matched? (Assume current to be IQ)
A. IE = IQ/2 B. IE = IQ C. IE = (IQ)2/2 D. IE = (IQ)2
Explanation: Due to symmetry of differential amplifier circuit, current IQ divides equally through both transistors.
