Abstract: A system and method is disclosed for selecting between two electronic signals, one of high quality, such as music audio, and the other of low quality, such as telephone call audio, in a smart phone, tablet or other device. In one embodiment, when the low quality signal is to be used this is accomplished by disabling the amplifier output to disconnect the high quality audio signal from the output port, rather than by means of a switch between the amplifier and the output port as in the prior art. This eliminates degradation of the signal due to the switch when the high quality signal is to be used. The amplifier typically has an associated feedback resistor network, and this may also be disconnected by means of a switch when the low quality signal is to be used, thus preventing distortion of the low quality signal due to the feedback network being a parallel load to the output port.

Abstract: An improved method for the placement and routing of compound elements, each comprising a series/parallel combination of nominally identical elements, is disclosed. The method treats each compound element as a separate cell (the sub-circuit construct commonly used in silicon chip design) so as to treat as a unit all the nominally identical elements that make up a compound value, and place them as a single group in the design of a chip. This results in the compound elements being placed as units and routed in such a way that all of the nominal elements are located together and any effects between compound values are thus relatively localized and optimally isolated.
