  1. Samuel Kerem Electronic Design The filter described below is useful for detecting a signal that’s closely surrounded by spurs, even when the task is complicated by the frequency of the signal of interest wandering by a few percent. For ...
  2. Abel Raynus EDN Thermocouples find widespread use for temperature measurement in systems. During system design or testing, you must observe the system's response at different temperatures. However, it's inconvenient to heat a thermocouple ...
  3. W. Stephen Woodward EDN The accurate transmission of analog signals over long distances in noisy industrial environments is a difficult design problem. One of the oldest solutions isolated current loops is still one of the best. This Idea For ...
  4. Herminio Martinez EDN One of the most popular circuits for amplitude control in oscillators is the soft-limiter circuit (Figure 1a). When the output voltage, V OUT (t), is small, diodes D 1 and D 2 are off. Thus, all of the input current, V IN ...
  5. Nick Ierfino Electronic Design In many situations, designers must control the phase of an output signal in order to make certain circuits work properly. At low frequencies, an op amp can be used to vary the phase. But as the frequency gets into the ...

  6. Kannan N Electronic Design Many products require an auxiliary dc output to power external devices or subsystems. If such subsystems are to be hot-connected, the auxiliary output must be protected against short circuits. Schemes using fuses are slow ...
  7. 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 ...
  8. 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, ...
  9. 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 ...

  10. 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 ...
