For the circuit in Figure P6.54, the parameters are Vcc=5 V and RE = 500 $22. The transistor parameters are ß = 120 and V₁ = ∞o. (a) De- sign the circuit to obtain a small-signal current gain of A¡ = io/is = 10 for RL = 500 2. Find R₁, R₂, and also the small-signal output resistance R.. (b) Using the results of part (a), determine the current gain for R₁ = 2 ks2. Vcc Us CCI = www www R₁ R₂ RE www Cc₂ RL 2° For the circuit in Figure P6.54, the parameters are Vcc=5 V and RE = 500 $22.
