Abstract :
This Paper will discuss an IC that performs all of the modulation, demodulation, filtering and handshake required to implement a MODEM that complies with the Bell 202 and CCITT 23 standards. The chip (double poly CMOS) uses switched capacitor techniques to operate at rates up to 1200b/s.
