This article investigates the impedance of the three standard passive circuit components (R, L, and C) as well as the frequency response of a PCB trace. It is shown that a PCB trace can be modeled as a resonant RLC network just like the standard components and effectively constitutes the fourth circuit component whose frequency behavior directly affects the impedance of the resistors, inductors, and capacitors on a PCB.

Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, an SMPS emits noise at its switching frequency and its harmonics. This article illustrates the procedure of designing filtering to achieve ultra-low output voltage noise with SMPS regulators.

High Voltage MLCCs Arc-Over Prevention

In applications in which energy conservation is critical, such as wind or solar inverters or electric-vehicle (EV) powertrains, distributing power at high voltage can help to reduce I2R losses. The DC link supplying the inverter can be 3 V to 400 V in an EV application, for example, or even higher for wind or solar-power conditioning. However, high operating voltages like these bring additional safety challenges not only for end users but also for components — even those with a suitable voltage rating stamped on the case.
