Detection of Electromagnetic Interference in Microcontrollers Using the Instability of an Embedded Phase-Lock Loop

This paper presents a combined hardware-software mechanism for the detection of electromagnetic interference of a microcontroller (μC) in daily usage. This detection mechanism is based on the instability of phase-lock loop embedded in the target μC. It can detect the presence of EMI with higher sensitivity than polling the hardware status of the μC internal… CONTINUE READING
