Abstract: In a system having multiple analog circuits that share a common power supply, where a change in the operational state of one circuit can have an effect on the performance of another circuit, a determination is made when any one of the circuits enters a state where its performance could be affected. Under such a condition, the other circuits that share the common power supply are placed in a state where their effect on the operation of the first circuit will be negligible. This state for the other circuits can be one of maximum current draw, so that subsequent operation by the other circuits will not alter the demands on the power supply.
