Basic electronic

Use the node-voltage method to find vo in the circuit shown. What is the voltage gain Av of this circuit? 2) Use the mesh-current method to find vo in the circuit shown. 3) The circuit shown below has 3 identical diodes, Is =10-14 A for each of them. a. Assume that the switch S is opened. Find the value of the current I required to obtain an output voltage vo = 2V. How much current will flow in RL ? b. [login to view URL] voltage vo if you know that the current I=1.7 mA and the current flowing in RL is 1mA. 4) The diode in the circuit shown is biased with a constant current source I. A sinusoidal signal vs is coupled through RS and C. Assume that C is large so that it acts as a short circuit to the signal. If RS = 260Ω, and I = 1mA, find vo/vs.
