Question: Consider the ac equivalent common-base circuit shown in Figure P6.61. The transistor has parameters (beta=110) and (V_{A}=infty). Determine (a) the voltage gain (A_{v}=V_{o} / V_{i}),

Consider the ac equivalent common-base circuit shown in Figure P6.61. The transistor has parameters \(\beta=110\) and \(V_{A}=\infty\). Determine

(a) the voltage gain \(A_{v}=V_{o} / V_{i}\),

(b) the current gain \(A_{i}=I_{o} / I_{i}\),

(c) the input resistance \(R_{i}\), and

(d) the output resistance \(R_{o}\).

R Rs = 1 k 1 10= 0.5 mA Rc= 4 Ro

R Rs = 1 k 1 10= 0.5 mA Rc= 4 Ro Figure P6.61
