Abstract :
This paper will report on a CMOS channel filter which contains transmit, receive and 50/60Hz rejection filters and two 600-ohm output drivers on a single die, designed for either +5 or single +12v, where operating power with active amplifiers is under 40mW. Switched capacitor techniques are used.
