- 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 ...20-10-2020
- 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 ...19-10-2020
- 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 ...15-10-2020
- 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? ...13-10-2020
- 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 ...12-10-2020
- 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 ...08-10-2020
- 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 ...06-10-2020
- 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 ...24-09-2020
- 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 ...17-09-2020
- 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 ...10-09-2020
