Reducing OLED driving chip´s simultaneous switch noise by coding

Inductance effects couldn´t be neglected in circuits with increasing of clock frequency and decreasing of process scale. In this paper, firstly it analyzes the theory related to simultaneous switch noise, describes a new method to reduce simultaneous switch noise by Bus coding. Then use this method to add a circuit to an OLED driving chip, the SSN testing result shows that Bus coding could reduce chip´s SSN effectively, and protect signal´s integrity.
