With increasing clock speed in high-speed digital design, proper impedance matching between the printed circuit board trace and the clock driver output is crucial for signal integrity design. Adding a series output resistor is a common technique to m

This paper discusses a novel approach to transforming a radiated-emission limit (e.g., CISPR 22 and FCC) from the far-field to the near-field region. The proposed approach combines data from a near-field scanner and a gigahertz transverse electromagn

With rapidly growing circuit density and the demand for low power supply to ICs in high-speed printed circuit board (PCB) design, board emission issues tend to seriously deteriorate the power distribution network (PDN) on PCBs. Among a variety of pro

Today's digital data lines are clocking at very high speed, in excess of 100MHz with rise time in the sub-nano second range. The effects of EMI radiation even from short traces are becoming significant and cannot be ignored. The use of resistive term
Electromagnetic interference (EMI) from mobile phones on hearing aids are investigated. Different operating modes of the hearing aid have different impact on the immunity of the device. An experimental study will be carried out to understand the impa

This paper describes a methodology to predict far-field (FF) emissions from a high-speed board based on the fields measured in the near-field (NF) region. The NF to FF transformation is based upon an empirical relationship between the measured fields

In today's high-speed board design, decoupling using on-board capacitors are necessary to provide stable DC power and to suppress radiated emission from the board. At the higher frequency beyond 300 MHz, one has to rely on the capacitance offered by

Based on an in-circuit measurement approach, a systematic EMI filter design procedure is developed to suppress the noise from a digital board to the power supply. The two-probe technique adopted for the in-circuit measurement allows the impedances of

Impedance matching is crucial in high-speed digital design to ensure signal integrity (SI). Accurate information of a device’s output impedance allows precise selection of series resistor to match the device’s output to the characteristic impedan
