Abstract :
This paper presents an small-size fully integrated mixed-signal DTMF receiver. It is able to operate in a wide range of voltage supplies (2.7V to 5V) while the current consumption is virtually fixed and kept small. It contains an smart digital detector and decoder algorithm that provides a very good speech immunity.
