Your help is required for this question.Thanks

In modern high-performance transistors, the gain is usually limited by the emitter efficiency, which implies D_EN_BW/D_BN_EL_E >> (1/2)(W/L_B)^2 Show that the common emitter input characteristics of such device are expected to be relatively insensitive to base width modulation. Sketch the expected form of the common emitter input characteristics if the transistor gain is not limited by the emitter efficiency: i.e., D_EN_BW/D_BN_EL_E ~ (1/2)(W/L_B)^2

Explanation / Answer

id = k1(vds- vgs)vt - vt2 )/2

for emitter cofiuration

id = k1(vs*vgs - vd2 )
