I live in this small city Gwalior, MP, India. I am a Physicist by education, Nuclear Scientist by Training, Electronics and Software professional by work. I am right now planning sensors and monitoring systems for water resource management and also developing technology to kill Pathogen in water / fluids by nano-second high voltage discharge pulses. Good quality drinking water is my primary concern right now. Some of our current work can be seen at www.asro.in

  • High-impedance FET probe extends RF-spectrum analyzer's usable range
  • Hello Steve Hageman, Nice work. Why gain isn't flat even at 200MHz. Perhaps just JET pair could have formed good buffer as you are limiting the amplitude due to protection diodes to just +/-100mV else signal will start loading and protection is adding capacitance of 2 diodes, terminating resistor and track on the PCB. I still like it as it can be a good cheap educational tool.

  • How to select precision resistors for 4–20 mA current loop
  • Yuval Hernik, Points are well taken and 4-20mA look sure has some serious consideration if wires run too long or likely to be subjected to ESD of 25kV. There is some smell of Vishay products publicity in it but I think that is all right as long as it serves a purpose. Dr. Shyam

  • LTC nano-power buck-boost DC/DC
  • I think it is a good development but I dislike those tiny packages and prefer some working spaces like SOIC / DIP etc..

  • Dual, low-noise JFET has low capacitance and high input impedance
  • I agree that Linear Systems has done a great contribution in not only developing the replacement JFETs but also their own better specifications. I want to try these parts myself. I have tried their other now noise low current parts also and improvement in input capacitance is good one for high frequency applications. 4pF is just great. Dr. Shyam
