Abstract
A multipath circuit is described that has multiple signal paths and various common components used for normal operation. Each of the multiple signal paths also has multiple circuit blocks defining the functionality of the signal path. A shared access path is provided through the third winding of a three-way transformer for each signal path. Multiple switches are provided in the multipath circuit that couple to the third winding in each of the multiple signal paths. The switches are also coupled to the various common components. Selected ones of these switches may be closed to provide a shared access path between a common component and one of the signal paths or between a common components and one of the circuit blocks in one of the signal paths.
