  1. Wallace Ly EDN A system designer must almost always face a trade-off in choosing the right part for an application. The trade-off usually involves performance, price, and function. An example is the issue of powering circuits from a telecom-voltage ...

  2. Santosh Bhandarkar EDN A simple and inexpensive electronic circuit uses a low-cost pushbutton switch to toggle the electrical power on and off. The circuit replaces a more costly and bulky push-push mechanical switch. load. The pushbutton switch ...
  3. Robert H. Russell Electronic Design I needed a simple LED indicator showing that a particular voltage level had been reached specifically, that a capacitor had charged to a particular potential. I was convinced that there must be a way that a ...
  4. Jayashree Raghuraman EDN The novel logarithmic amplifier in Figure 1 relies on the exponential charging characteristics of a simple RC circuit. The expression for the time, T, required for a capacitor, C, to reach a voltage (V IN V K ) from 0 V, ...
  5. Michele Costantino EDN This Design Idea describes a simple and effective way to provide optoisolation for devices connected on the I 2 C bus (Figure 1). It improves on an earlier version (Reference 1). SDA and SCL are on the bus master’s side ...

  6. Alex Birkett EDN Traditional current sources and voltage-to-current converters based on instrumentation and operational amplifiers offer high output impedances at low frequencies because of the amplifiers' good low-frequency CMRR ...

  7. Jim Tonne Electronic Design With a handful of low-leakage passive components and two high-impedance op amps, you can build a sine/square-wave generator with output period of a minute and more. The circuit of Figure 1 generates sinusoids down to ...
  8. by John Ardizzoni, Analog Devices Eelctronic Design Europe In consumer electronics applications, which tend to be lower in frequency and less demanding than typical clock-buffering applications, inexpensive high-speed op amps (~100-MHz bandwidth) ...

  9. Stephen Woodward EDN For at least four decades, dual-slope integrating A-to-D conversion has formed the core of most every digital multimeter and many industrial and instrumentation applications besides. Elegant in its simplicity, a DSADC ...

  10. Attaining optimal SNR performance from an ADC isn’t just a matter of providing a low noise signal to the ADC’s input. Providing a low noise reference voltage is just as important. While reference noise has no effect at zero-scale, at ...
