PROBLEM TO BE SOLVED: To provide a novel and improved method and a circuit for supplying an interface signal to plural integrated circuits(IC). SOLUTION: The circuit for generating an interface signal between first and second IC is provided with a reference circuit for supplying a reference signal, an interface circuit and a circuit element. The interface circuit is connected to the reference circuit so as to operate being mounted on the first IC, receives the reference signal and a data input and generates the interface signal. The circuit element is coupled to a control circuit so as to operate being mounted on the second IC, receives the interface signal and supplies an output signal. The reference signal can be a voltage or current signal as well and can be generated by the first or second IC. The interface circuit can be mounted in a current mirror coupled to a switch array and over-sampling is enabled to make filtering easy.
