App note: Supercapacitors and the potential to revolutionize energy storage power delivery
All about supercapacitors explained in this app note from Abracon. Link here (PDF) While batteries have been a mature technology for over a century, the need for energy storage solutions with faster charging and discharging cycles than traditional batteries has led to the search for a new alternative. Although conventional capacitors offer the fastest charging […]
App note: Ferrite beads basic operations and key parameters
Here’s app note from Abracon for EMI suppression using ferrite beads. Link here (PDF) A ferrite bead is a passive electrical component used to suppress high-frequency noise, EMI, and crosstalk in electronic circuits. They come in different shapes and sizes; some beads are available in the form of clamp-on cores, like the ones found at […]
App note: Benefit of measuring crystal In-Circuit
App note from Abracon on measuring in circuit oscillator loop of most MCUs with internal amplifier unit to ensure proper operation. Link here Growing technology trends including green energy initiatives and the explosive growth of IoT centric solutions, are driving the need to accurately define the frequency-selective network in order to achieve the best possible […]
App note: Common mode chokes basics and applications
App note from Abracon about EMI filtering with CMCs. Link here Common mode chokes are used in both power and signaling circuits. Data lines in electronic communications systems usually exist as pairs where they transmit signals of equal amplitude but opposite polarity. These lines are known as differential signals or pairs, such that the transmitted […]
App note: 18pF crystals may not oscillate with energy saving MCUs
App note from Abracon about problems due on large crystal capacitive loading on smaller sized MCUs. Link here (PDF) The 18pF plated Quartz Crystals may no longer be the ideal choice for a typical clocking circuit using an off-the- shelf MCU. As silicon geometries have shrunk over the last decade, the Pierce oscillator loop embedded […]
App note: PCB trace vs. chip antenna design considerations
Abracon lists the requirement which antenna type best fit to your application. Link here (PDF) The modern urban environment poses a challenge to high-speed designs involving Cellular, GNSS, WiFi/Bluetooth/BLE/ZigBee and LPWA protocols: the reflection, refraction, scattering, diffraction, polarization and absorption of signals necessitates highly efficient RF chains. Of all components in the chain, the antenna […]
