Question #1: (10 pts) The voltage amplifier below has an open circuit voltage gain of A V , input resistance R in and output resistance R out . D 2 is a Zener diode with a break-down voltage V z0 = 6V . Use the CVDM for any other diodes. a) The voltage amplifier is connected with a DC source V s and a load resistance R L . Sketch the voltage transfer characteristic (V out /V s ) , indicating all important points and the slope . Derive an expression (of the form y = mx + b) for the voltage transfer function of the circuit in the linear region. [4 pts.] Figure 1.1 b) Assume R s = 100 , R
