A single chip mixed digital/analog signal processor in 1.2 mu CMOS interfacing 4 analog subscriber lines to the PCM digital System 12 exchange

For the development of a new generation line circuit a 4 channel speech processor was designed and fabricated in a 1.2 mu CMOS technology. The circuit includes digital signal processing for receive and transmit signals as well as the analog frontend interfacing four subscriber lines to a PCM digital exchange. The device is operating on a single 5 V power supply.<>
