Abstract:
An apparatus includes a first amplifier circuit and a second amplifier circuit. The first amplifier circuit has a first output coupled to a first load circuit in a multi-output mode, and the second amplifier circuit has a second output coupled to a second load circuit in the multi-output mode. The apparatus further includes a first divert circuit and a second divert circuit. The first divert circuit is configured to divert a first portion of a first amplified signal from the first amplifier circuit to the second load circuit in the multi-output mode. The second divert circuit is configured to divert a first portion of a second amplified signal from the second amplifier circuit to the first load circuit in the multi-output mode.
