Abstract:
A 5 Ringer Equivalent Number (REN) ringer circuit has a wave generator. A flip-flop is coupled to the wave generator and has a non-inverting and an inverting output. A high voltage level translator is coupled to each of the non-inverting and the inverting outputs of the flip-flop. A source follower buffer is coupled to an output of each of the high voltage level translators.
