A trans-conductance amplifier can be represented by a model with: Input resistance Ri = 2k2, a dependent current source with magnitude (20 mA / V) vi (where vi is the voltage across Ri), and an output resistance Ro = 5kN. The input of the amplifier is connected to a source with Thevenin resistance Rs = 500 2. The output of the amplifier is connected to a load RL = 1k2. Determine, 1) The voltage gain, Av = vO / vS, where vS is the open circuit voltage of the input source and vO is the voltage across the load. 2) The current gain, A1 = iO / iS, where iS is the current provided by the input source and iO is the current through the load.
