Earl McCune, RF Communications Consulting ABSTRACT Achieving low power supply noise does not automatically assure low EMI. Fortunately a PCB layout designed for low EMI does automatically result in low noise. The techniques presented here do achieve both goals. INTRODUCTION Much has been written, spanning several decades, on how to design printed circuit layouts for low … [Read more...]
