Technical Tidbit - August 2007:
This month's Technical Tidbit discusses EMI induced by mobile phones into nearby electronic circuits. Significant voltages can be induced into circuit features of a small electronic product that is in contact with a mobile phone, such as in a pocket or purse.
Abstract: Cases of circuit failures caused by mobile, or cell, phones are starting to be reported. Electromagnetic Interference (EMI) from mobile phones has been shown to produce hard and soft failures in circuits. Data is presented to show the possible amplitude of EMI induced into a common printed wiring board layout feature. The induced signal is of sufficient amplitude to corrupt signals and in some cases cause hard failures.
