Introduction A circuit breaker protects sensitive load circuits from excessive current flow by opening the power supply when the current reaches a predetermined level. The simplest circuit breaker is a fuse, but blown fuses require physical ...
In [1] a cascode connection of two MOSFETs helped eliminate the Miller effect and significantly improve power factor correction (PFC) performance. Recall that the Miller effect is a very large increase in a transistor’s apparent input ...
TEC (thermoelectric-cooler) temperature-control systems often have limited stability. The causes of these limitations are the thermal properties of the system, not the performance of the control electronics. Real-world thermal-control systems incur ...
Most engineers know about the solid-state refrigerators called Peltier devices or, more commonly, TECs (thermoelectric coolers) and how they can actively cool temperature-sensitive electronic components, such as optical detectors and solid-state ...
The traditional method of controlling the upper cutoff frequency in the basic inverting-amplifier circuit of Figure 1 is to add capacitor C in parallel with R 2 . The value of C controls the cutoff frequency. R 1 and R 2 independently establish the ...
Design Note 568 Attaining optimal SNR performance from an ADC isn’t just a matter of providing a low noise signal to the ADC’s input. Providing a low noise reference voltage is just as important. While reference noise has no effect at ...
Tom Gross EDN It can be difficult to generate a high-voltage supply from a medium-voltage input, especially if you need a surface-mount design. It is difficult to find surface-mount components with the necessary specs, especially the transformer ...
Our op amp family has expanded with industry-leading speed versus supply current. The LTC6258/LTC6259/LTC6260 family (single, dual, quad) provides 1.3 MHz gain-bandwidth product at a super low 20 uA supply current, with 400 uV maximum offset ...
Henry Santana Electronic Design Europe The general approach to an electronic load is to use a transistor across the input terminals so the current flows from drain (collector) to source (emitter). A resistance is effected by causing a current flow ...
Kurk Mathews EDN As the demand for networking equipment grows, the need arises for a 48 V supply that can power telecommunication lines. The circuit in Figure 1 delivers 24 W at 48 V from a 5 V input. One of the biggest challenges in this design is ...
