6.62 Figure P6.62 shows an ac equivalent circuit of a common-base amplifier. The parameters of the transistor are ẞ=120, VBE (on)=0.7 V, and VA∞o. (a) Determine the quiescent values Ico and VCEQ. (b) Find the small-signal voltage gain A, Vo/V. (c) Find the small-signal current gain A₁ = 10/1. Figure P6.62 1= 1.5 mA ww R₁ =5kQ R₂- 2.8 ΚΩ Cc R₁== 10 ΚΩ
