Abstract: The present invention provides a signal processing system and associated method. The signal processing system includes converter(s) for conversion between digital and analog, each converter includes multiple serially coupled units forming multiple frequency interfaces respectively associating with different frequencies, and each converter is partitioned, at a selected frequency interface, to a first portion and a second portion respectively formed in the first chip and the second chip. The partitioning frequency interface is selected to reduce implement cost.

Abstract: An amplifier circuit is disclosed. The amplifier circuit includes a detection circuit, a control amplifier circuit and an output stage. The detection circuit detects disturbances occurring in a first supply voltage and provides detection results. The control amplifier circuit controls a first voltage provided to a first control node and a second voltage provided to a second control node in response to the detection results. The output stage circuit includes a first output power transistor coupled to the control amplifier circuit at the first control node and a second output power transistor coupled to the control amplifier circuit at the second control node. The first voltage and the second voltage are controlled differently when a disturbance is detected to have occurred.
