An analog record, playback, and processing system on a chip for mobile communications devices

We present a low-power chip for nonvolatile storage and conditioning of voiceband analog audio signals and nonvolatile storage for use in mobile communication devices. The system allows for direct interface to acoustic transducer elements and provides signal conditioning to gain adjust, multiples, f...
