Managing Director

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

  • Control an LM317T with a PWM signal
  • This design will cause ripple due to 1M and 100nF averaging RXC time constant. Shyam Sunder Tiwari, PhD Physics www.sensorstechnology.com/ www.asro.in/

  • Low-power CMOS oscillator has push-pull output
  • Output current from each output is sourced to maximum 25mA by the device while ground current that may flow during skew of about +/-1ns from expected 10ns transition time is limited by the ground current capability of the IC which is typically 50mA. 50pC charge not likely to damage the IC output stage even with repeated performance over few years. Skew current sure will flow in wired OR logic here. Shyam Sunder Tiwari, PhD Physics www.sensorstechnology.com/

  • 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.
