  1. Instrumentation amplifiers serve in a variety of applications that need to extract a weak differential signal from large common-mode noise or interference. However, designers often overlook the potential problem of RF rectification inside the ...

  2. It is always desirable to use a low-battery indicator that consumes as little power as possible. For a 9 V, 450-mAhr alkaline battery, a 50-µA low-battery indicator can by itself run the battery down in a little more than a year. ...

  3. Amplifiers with positive feedback are the bases of signal-grade pulse-forming circuits. This setup ensures a triggerlike operation in which the input signal crosses the input-threshold level; in most cases, the input signal is a voltage signal. The ...

  4. You can improve a capacitive-sensor circuit with a modulator and an RF transmitter (Reference 1) by modifying the modulator portion to obtain better accuracy. More improvements result from adding a “negatron” circuit, a configuration ...

  1. Electric vehicles, large-scale battery storage stacks, home automation, industrial, and telecom power all require converting high voltages to 12 V, where dual polarity rails are required for powering amplifiers, sensors, data converters, and ...

  2. Figure 1a shows the classic implementation of an integrator. The circuit has two properties that may be undesirable in same applications: It necessarily inverts, and it requires a split-supply or midsupply reference. Figure 1b shows an ...

  3. Because they use practically no bias current (a useful feature in itself), JFETs also have practically no current noise. This feature means that you can use JFETs in very-high-resistance circuits and obtain good noise performance. JFETs are also ...

  4. Plumbing a laboratory with a standard frequency makes a lot of sense if the lab uses multiple frequency counters, spectrum analyzers, and other frequency-dependent test equipment. Rather than spending time keeping all of the instruments' ...

  5. Although the prevailing number set in electronics is binary, human-machine interaction uses a decimal-number set. For this reason, designs often require the use of amplifiers with gain programmable in steps in the power of 10. Currently, Analog ...

  6. EDN Phase shifters find use in a variety of circuits, but variation in amplifier and capacitance tolerances usually makes it difficult to control the exact phase shift that precise control circuitry requires. The circuit in Figure 1 can control the ...
