The DC analysis results for obtaining the small-signal equivalent (SSE) model parameter values of the transistor placed in the circuit given in Figure 1 are gm = 4mA/V and ro -> ∞ (open circuit). The resistor values are given as follows: R1 = 40kΩ, R2 = 40kΩ, RSi = 10kΩ, RD = 100kΩ and RS = 1kΩ. a) Draw the AC model of the whole circuit in Fig. 1 by replacing the transistor with its SSE model. State the type of the transistor and circuit topology. (Drawing the AC model of the circuit at the last step is sufficient, showing the steps of drawing is not wanted.) b) Rin =? RO = ? Avo =? Av =? Gv = ?c) If vin = 10mV, then find vO = ?
