Norton equivalent composed of a current

Reference no: EM131018119

A CG amplifier operating with gm = 2 mA/V and ro = 20 kΩ is fed with a signal source having a Norton Equivalent composed of a current signal isig and a source resistance Rs =20 kΩ. The amplifier is loaded in a resistance RL = 20 kΩ. Find Rin and io/isig, where io is the current through the load RL. If RL increases by a factor of 10, by what percentage does the current gain change? Can you see the effectiveness of the CG as a current buffer?
