Abstract

We have designed an audio and data processing circuit for cordless telephone that contains a scrambler, a modem, and amplifiers for the microphone and receiver. The circuit can be fabricated into a single chip IC. The newly developed baseband signal processor is divided into two: an analog block made from a bipolar process and a digital block made from a CMOS process. The whole block can be fabricated using BiCMOS process technology
