<!--EE 42, Midterm #2, Fall 1994)--> In the circuit below, the amplifier parameters Ri , Ro and A are known, as are the voltage Vs and resistance Rf. Find the Thevenin equivalent circuit seen at terminals x and y in terms of these known quantities. Problem #3. [20 points] In the circuit below the nonlinear element S has Vs - Is relation Is = Vs^2, Is in mA., Vs in V. Find the value of the voltage Vout in this circuit. 7 PM file:///C|/Documents%20and%20Settings/Jason%20Raft...-%20Fall%201994%20-%20Murphy%20-%20Midterm%202.htm (2 of 4)1/27/2007 4:43:3
