(i) Derive an expression for the input resistance of this circuit in terms of the [5 mutual conductance of the transistor gm and its current gain β. we require an amplifier with a gain of-100, an output impedance of 1kΩ and an input impedance of 1k2. The transistor has a current gain of 200. (i) State the value of Rc required for the output impedance given above and 12 (ii) Find the collector current and hence determine the value of Rg needed to [4] (ii) Find the value of Rp needed to obtain the input impedance given above.[1 (iv) In order to obtain a lower cut off frequency of 60Hz, calculate the value of [11 find the mutual conductance gm of the transistor in this circuit. obtain this current. Cin required. (v) Calculate appropriate values for Cout and CE.
