Abstract

The audio processing function is combined with a 0 dBm transmitter using 0.25 /spl mu/m BiCMOS technology for portable wireless applications. Reference suppression is better than 60 dB. It operates over 1.8 to 2.8 V and consumes 26 mA. As part of a highly integrated two-chip transceiver system, it enables a low cost solution for analog cordless telephones.
