Use of Grounding Techniques in PCB Design to Prevent Electromagnetic Interference (EMI)
Grounding is the first line of defense against Electromagnetic Interference (EMI). Design for Electromagnetic Compatibility (EMC) involves utilizing techniques like EMC filters, shielding and circuit partitioning to ensure good EMC performance. However, properly planning and implementing grounding in your design, effectively reduces emissions, common mode noise and interference due to capacitive and inductive coupling and […]
PCB Design Guidelines for Reduced Electromagnetic Interference (EMI)
Electromagnetic Interference (EMI) is unwanted electromagnetic energy that disturbs the proper functioning of an electronic device. All electronic devices generate some amount of electromagnetic radiation since the electricity flowing through the circuits is not fully contained. How does Electromagnetic Interference (EMI) occur? When current flows through a closed path it creates a magnetic field that […]
EMC vs EMI – Compatibility, Principles & Mechanism Comparisons
Electronic systems are not completely closed systems. The current flowing through the circuits is not fully contained; rather it generates electromagnetic energy that can propagate around the circuit and tends to produce disturbance voltages in and around the system. Electronic circuits, therefore, have this tendency to radiate or pick up this undesired electromagnetic energy and […]
Inverting/Dual Rail Supply Designing Guide
The remarkable property of a dual-rail supply is that compared to the positive DC voltages, whose voltage is positive concerning GND potential, this supply can also provide negative voltage. DC supplies are more commonly used in everyday electronics than AC supplies. One way to get DC voltage is by converting it from AC voltage or […]
