  1. EDN A true-differential, power-source-free, high-input-impedance amplifier with bipolar output would present distinct advantages in remote devices. Such an amplifier, with its bipolar output, would be a better choice than a unipolar, 4- to 20-mA ...

  2. Electronic Design Opto-electronic systems frequently require temperature stabilization for components such as laser diodes, photodiodes, prisms, and lenses. The established method for providing stabilization is to attach a resistive temperature ...

  3. EDN Some battery-powered devices require large amounts of current in a short period of time but spend most of the time in sleep (power-down) mode. The momentary large-load current demands large batteries to meet the time requirement, even though ...

  4. Circuits Supply Diodes ZTX1047 ZTX869
    Electronic Design The converter described below, based on a silicon bipolar-junction transistor (BJT), can operate at as low as 250 mV, which is probably a record for a converter not based on a JFET or germanium transistor. How is this possible? ...

  1. EDN Under certain conditions, ESD events can damage digital circuits by causing latch-up. For example, when ESD triggers them, parasitic transistors normally formed as parts of a CMOS device can behave as an SCR (silicon-controlled rectifier). Once ...

  2. EDN Many power-supply designers like to have a regulator latch off in the event of an overcurrent situation or other fault condition. Yet, many PWM controllers do not internally support this latch-off function. Most do, however, have a power-good ...

  3. EDN Texas Instruments' UCC3895 offers a good base for building a high-efficiency, pulse-width-modulated, switched-mode power supply that suits either current- or voltage-mode control. Designed for driving a full-bridge power inverter using two ...

  4. EDN The battery monitor circuit in Figure 1 can be very helpful for any portable equipment powered by two 9-V batteries. When both batteries are in good health, an LED produces short bursts of light every second. If either or both batteries drop ...

  5. Circuits Supply Maxim MAX6025 MAX1087
    EDN If you use an ADC to monitor a system's power-supply voltage, you may encounter situations in which the supply voltage exceeds the ADC's reference voltage (Figure 1). However, the ADC's input voltage cannot exceed its reference ...

  6. EDN This Design Idea presents a self-powered, precision-active-load circuit that improves on a previously published design (Reference 1). Added features include a wider operating-voltage range of 2 to 50 V or higher and several flexible ...
