Why do engineers still use discrete JFETs? For ultra-low noise, high input impedance, low input capacitance and excellent linearity — critical for weak-signal front ends. Read more: wix.to/ArtoW60 #AnalogDesign #JFET #Electronics #LowNoise
JFET Design Spotlight: Rethinking the Audio Op-Amp — short read on why the first design is rarely the final one and how disciplined critique leads to better analog circuits. Read: wix.to/G0sMrPM #JFET #OpAmp #AnalogDesign #Audio
JFET Design Spotlight: How early OCR sensors influenced 45 years of FET design. Short, technical, and full of lessons for analog engineers. Read more: wix.to/OF6pLr8 #JFET #Analog #Electronics #OCR
The LSK489 combines: • 1.8 nV/√Hz typical noise voltage • Industry-leading 4 pF typical input capacitance • Monolithic dual JFET matching and thermal tracking #JFET #AnalogDesign #LowNoise #Sensors #Instrumentation #Hydrophones #MEMS #ElectronicsDesign #PrecisionAnalog
Low noise alone won’t save high-impedance sensor signals. Input capacitance and front-end choices can be just as critical. Quick read for engineers: wix.to/SQpBT9t #AnalogDesign #Sensors #Electronics #Engineering
JFET Design Spotlight: Maximum Power Point Test Controller — a neat father-daughter build turned MPPT tester. Learn how three JFETs perform distinct functions for accurate solar panel characterization. Read more: wix.to/AYLn0oK #Solar #MPPT #JFET #Electronics
New blog: Photodiode Preamps — learn why low input capacitance and low input noise matter for photodiode amplifiers and how devices like the LSK489 can help. Full post: wix.to/odx5lUp #Photodiode #Electronics #LowNoise #OpAmps
Updated SPICE models for the LSK389 (A/B/C/D) derived from real device data — get more accurate simulations and closer-to-real-world results. Details: wix.to/xGf9owV #SPICE #LSK389 #Electronics
Why the analog front end matters: tiny signals need ultra-low-noise, tightly matched components like the LSK389 dual JFET to be detected reliably. Read more: wix.to/PIJLnKR #AnalogDesign #Sensors #Electronics
Single-JFET phase splitter for audio — a compact solution for clean 0°/180° outputs, low DC offset, and balanced signals. Read the design notes: wix.to/Nnq677s #JFET #Audio #CircuitDesign #Electronics
GPUs are famous — but semiconductors for signal integrity, timing, and control make AI systems actually work. Learn how these overlooked parts shape AI infrastructure: wix.to/1AuCaTh #AI #Semiconductors #Hardware #SignalIntegrity #Engineering
New Design Spotlight: A ±1kV soft‑start circuit that fixed startup failures in electron microscope HV amplifiers. Fast, practical reading for HV designers. Read more: wix.to/dJu7jSQ #Electronics #HV #CircuitDesign
The BF862 is gone — the LSBF862 isn’t just a replacement, it’s an upgrade. Short read on why engineers prefer LSBF862 for ultra-low-noise and stability-critical circuits. wix.to/f1ivNvS #electronics #LSBF862 #engineering #lownoise
New post: A Discrete Design for a Guitar Compressor — notes from 8 years of testing classic compressors and building a better-response design. Read: wix.to/J417o4q #GuitarPedals #DIYPedal #AudioEngineering #Tone
Improve photodiode amplifier bandwidth by reducing input capacitance. See how the LSK489 ultra-low noise, low-capacitance dual JFET helps designers hit higher speeds with better stability. Full article: wix.to/V0JDumI #analogdesign #jfet #photodiode #lownoise
Temperature-induced error in RF RMS measurements? This constant-temperature substitution design using pico‑amp diodes and JFETs offers a clever fix. Read the article: wix.to/kMapotA #rfengineering #analogdesign #electronics #lownoise #linearsystems
Obsolete parts are a bigger headache for analog designs — small differences can break performance. Learn practical fixes engineers use to keep production on track: wix.to/IXderos #analogdesign #obsolescence #electronicsengineering #EE #hardwareengineering
New from Linear Systems: SPICE model for the PAD Series SSTPAD10 low‑leakage diode is now available for LTspice and other SPICE tools. Improve leakage and capacitance simulations and speed up development. Read more: wix.to/x0iVQZ8 #SPICE #Electronics #LTspice
