High CV MLCC DC BIAS and AGEING Capacitance Loss Explained

By European Passive Components Institute Posted On 1.3.2019

Source: Original EPCI article

by: Tomas Zednicek, EPCI

MLCC capacitors are dominating today’s capacitor market enabling high grade of electronics miniaturization. The continuous downsizing and use of higher and higher dielectric constant materials for MLCC class II capacitors has however resulted in worsening of some electrical parameters stability such as capacitance drop at operating conditions. Thus, in consequence, what can be considered as an enabling technology for consumer and wearable applications may pose some risk if used in critical applications such as automotive, safety, medical or industrial sector, that are also in need for continuous miniaturization.

Passive Filter Design Concept of Buck Regulators for Ultra-Low Noise Applications

By Monolithic Power Systems Posted On 22.2.2019

Source: Monolithic power article

Switched-mode power supplies (SMPS) have the advantage of high efficiency compared to traditional low-dropout (LDO) regulators. Due to its switching nature, a 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. (more…)
