JFET vs. MOSFET: Choosing the Right Technology for Precision Analog Applications Field-effect transistors are foundational building blocks in modern electronics, but not all FETs are optimized for the same tasks.While MOSFETs dominate digital circuits, power management, and switching applications, JFETs continue to play a critical role in low-noise, high-impedance analog front e...

New on the blog: Photodiode Preamps — why low input capacitance and low equivalent input noise matter for clean photodiode detection. Learn how device choices like the LSK489 dual FET (≈3 pF input capacitance) compare to typical JFET op amps and improve low-noise performance. Read more: https://wix.to/w85E7ns

Photodiode Preamps In some JFET op amps such as the AD743, the input capacitance is in the order of 18 to 20 pF. In comparison, with an LSK489 dual FET, the input capacitance is in the order of 3 pF, which will be suitable for low noise photodiode applications. In this section we will see why it is important to have l...
