How to Minimize EMI – by Lee Hill

Consultants Network

Electrical noise and EMI are the bane of every electronic circuit, and there is no easy way to minimize them. In this talk, we will review:

• Why Electrical Noise Problems Arise
• How to Analyze Them
• How to Solve and Avoid Them
• Systematically analyze and solve noise problems by using the noise model to create and analyze a noise circuit schematic
• Minimize radiated EMI by designing low inductance signal interconnects
• Understand ground loops, how to represent them in an equivalent circuit, and how to eliminate them
• Clearly identify and manage the three different types of “ground” in schematics and physical circuits
• Identify “accidental antennas” in new designs
• Understand and measure common-mode current in emissions and immunity problems
• Improve the quality of sensor and instrumentation signals in the presence of noise
