  1. Capacitor-powered electronics is at the core of green design
    The concept of using supercapacitors (also known as ultracapacitors, supercaps, etc.), and replacing the batteries in portable micropower applications (Ref. 1) is gaining momentum. In fact, it has become one of the more...

  2. Program resistance in a bridge circuit
    Sensors such as strain gages, RTDs (resistance temperature detectors), and thermistors produce a resistance that’s proportional to force or temperature. If you measure a sensor’s resistance, you can...

  3. Circuit improves on temperature measurement
    When current pulses with a stable IHIGH/ILOW ratio modulate a semiconductor junction, the ensuing voltage difference (for example, ΔVBE for a bipolar transistor) is a linear function of the absolute (Kelvin)...

  4. Electromechanical damping stabilizes analog-meter readings
    Before shipping moving-coil meters, manufacturers may short-circuit the meters' terminals with a length of wire, which provides effective electromagnetic damping and results in better immunity to external mechanical...

  5. Improved frequency modulator uses «negatron»
    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...
