Characterizing & Debugging EMI Issues for Wireless and IoT Products

An increasing number of manufacturers are adding or retrofitting wireless technology into new or existing products. These products typically include mobile, household, industrial, scientific, and medical (ISM) devices. This transition towards “everything wireless” is in full swing, and with it comes problems with electromagnetic interference (EMI) from the product itself interfering with sensitive on-board cellular, GPS/GNSS, and Wi-Fi/Bluetooth receivers. Read on to find out what to do about it.

Efficient Sensitivity-Aware Assessment of High-Speed Links Using PCE and the Implications for COM

While a channel may pass a test, the remaining margin and thus its resilience against geometry or material variation in production may not be observable. However, such variations are critical because they may impede the performance or cause high volume manufacturing (HVM) products to fail. This coalition of authors has developed and demonstrated a polynomial chaos expansion (PCE) flow to analyze a full-featured 100GBASE-KR4 link starting from geometry specification to Channel Operating Margin (COM) margin at the receiver. Read on to see their award winning paper on the subject.
