  1. Petre Petrov EDN Many of the sensors capturing information from the world around us are resistive. A few examples are NTC, PTC, LDR, contact sensors. If we convert the resistance of the sensors into frequency or pulse duration, these parameters can ...
  2. Jordan Dimitrov EDN Designers often use VFCs (voltage-to-frequency converters) to perform A-to-D conversion in data acquisition systems that require strict monotonic response, high resolution, reduced noise and moderate speed. The VFC produces a ...
  3. Peter Demchenko, Vilnius, Lithuania EDN This Design Idea shows how to calculate the inductance of a multilayer air-core coil using only its dimensions and resistance. If you know the dimensions and the number of turns on an air-core coil, you can ...
  4. Raju Baddi, Tata Institute of Fundamental Research, Pune, India EDN Part 1 It is sometimes useful to listen to an audio signal at a test-circuit point. The 4069, with its high input impedance and sufficient output drive current of approximately 6.8 ...
  5. Raju Baddi, Tata Institute of Fundamental Research EDN This Design Idea describes a simple way that you can use one hex-inverter package of an unbuffered HD14069UB CMOS (Reference 1) to make four test gadgets: a logic probe with well-defined ...
  6. Application Note AN143 December 2013 Michel Azarian, Will Ezel Presented is a simple model that can be used to accurately predict the level of reference spurs due to charge pump and/or op amp leakage current in a PLL system. Knowing how to predict ...
  7. Raju Baddi EDN This automatic pulse generator (figures 1 and 2) is a test gadget that senses a probed contact to a pair of terminals under test and automatically issues a momentary power pulse to them once proper contact is made. These terminals ...
  8. Application Note AND9151/D November 2013 Creating and distributing clock signals are the heartbeat of digital systems. Today's high-end systems demand extremely low noise clock signal integrity. Jitter, and more recently, phase noise, are the most ...
  9. Martin Tomasz, Sageloop Designs EE Times Current-sense amplifiers can monitor battery or solar cell currents, and are useful to estimate power capacity and remaining life. However, if the battery or solar source is a single cell, it’s ...
