Suppose that a current source is feeding an amplifier with input resistance of 5k ohms. The current source can be approximated with it Norton equivalent circuit delivering Norton current of I=50mA and having a resistance of 10k ohms.
a) What percentage of the ideal (max) signal is being delivered to the amplifier?b) Do you want your (current) amplifier to have a large or a small input resistance? What is the ideal value for the input resistance of a current amplifier?c) Do you want your current source to have a large or a small output (Norton) resistance? What is the idea value for the output resistance of a current source?
