The magnitude of the mid-band voltage gain of the circuit

The magnitude of the mid-band voltage gain of the circuit shown in figure is (assuming h_fe of the transistor to be 100)

Mid-band voltage gain

(A_{V_s}) =	V₀
	V_i

=	-h_ƒeI_b(10k)
	I_b(10k) + I_bh_ic

=	-h_ƒe(10k)
	10k + I_ic

A_{V_s} =	- 100 × 10k	(neglecting h_ie)
	10k

|A_{V_s}| = 100
