The curve obtained in the input characteristics of a BJT in common-emitter (CE) configuration is _______.
Similar to a forward diode curve
In the Common-Emitter (CE) configuration of a BJT:
- The input characteristic plots base current (IB) vs base-emitter voltage (VBE).
- The base-emitter junction is a forward-biased p-n junction — so the curve has the same exponential shape as a forward-biased diode.
- Current remains negligible until VBE crosses ~0.6–0.7 V (for Si), then rises steeply.
This is unlike a reverse breakdown or a horizontal line — it is a forward diode curve.
