Question

when a bjt amplifier is biased for linear operation, vbe should be about 0.7 v
select one:
○ true
○ false

Explanation:

For a BJT (Bipolar Junction Transistor) amplifier to operate in the linear (active) region, the base - emitter junction must be forward - biased. For silicon BJTs (which are the most common), the forward - bias voltage \(V_{BE}\) is approximately \(0.7\space V\). This forward - bias ensures that the transistor can amplify the input signal linearly. If \(V_{BE}\) is too low (e.g., less than \(0.5\space V\) for silicon), the transistor may be in the cut - off region and not amplify. If \(V_{BE}\) is too high, the transistor may enter the saturation region and also not provide linear amplification.

Answer:

True
