This article discusses the distribution of a PCB return current underneath top trace for the microstrip configuration. Next month’s article will discuss the distribution for the stripline configurations.
This article discusses the creation of a common-mode current in a typical circuit and explains the effectiveness of a common-mode choke on differential-mode and common-mode currents.
Scientists have discovered a surprising phenomenon that could result in smaller, lower-power memory and computing devices.
This article is devoted to the current method of the conducted emissions measurements.
The paper discusses the importance of understanding the current distribution below a printed circuit board trace.
It is well known (but often forgotten) that the concept of inductance, without defining a complete loop of current, is completely meaningless! Some books give inductance of a length or wire, some people talk about the inductance of a via, and still others talk about the inductance of ground braids, etc. All these discussions about inductance ignore the requirement for a complete loop before the total or loop inductance can be discussed in any meaningful way.
Furor and controversy are words which describe the process by which standards committees decide the value of the resistor in the leakage current measuring network. However, the different specified resistor values create no more than a 6.25% error for the value of the leakage current.
This article dispels some of the misconceptions surrounding inductance and to encourage electrical engineers to think more clearly about these physics.
Fox Electronics, a leading global supplier of frequency control solutions, now offers the F300 series of HCMOS oscillators which feature low voltage and low current consumption. The 1-volt oscillators incorporate a standby function that reduces the oscillator’s current consumption to 5 micro amps for more efficient power usage.
