The voltage-doubler circuit in Figure 1 can convert 2.5 V dc to 5 V dc or 1.8 V to 3.3 V. Most voltage doublers use an inductor, but this circuit doesn’t need one. The circuit uses a capacitor, C, by charging it through serially connected ...
It is known that the p-n diode can be the basis of an accurate thermometer for cryogenic temperatures up to about 200 C. A constant current is maintained through the diode and the voltage across it gives an indication of the temperature. The ...
Numerous applications require the measurement of very low resistances, including but not limited to fuse integrity analysis, relay characterization, and superconductor evaluation. There is a wide range of commercially available equipment designed ...
The need for conditioning low-level ac signals in the presence of both common-mode noise and differential dc voltage prevails in many applications. In such situations, ac-coupling to instrumentation and difference amplifiers is mandatory to extract ...
LVDTs (linear variable differential transformers) are electromechanical measuring devices that convert the position of a magnetic core into electrical signals. You generate these signals via excitation on the primary side. The results on the ...
Almost all precision voltage-to-frequency converters (V-F) utilize charge pump based feedback for stability. These schemes rely on a capacitor for stability. A great deal of effort towards this approach has resulted in high performance V-F ...
Figure 1, fast rise time pulse generator, switches a high grade, commercially produced tunnel diode mount to produce a 20 ps rise time pulse. O1’s clocking (trace A, Figure 2) causes Q1’s collector (trace B) to switch the capacitively ...
High-speed DACs offer differential outputs, but, for low-end ac applications or high-precision level-setting applications, a single-ended current-output DAC with a differential-conversion circuit provides a novel approach to generating ...
Introduction High voltage buck DC/DC controllers such as the LTC3890 (dual output) and LTC3891 (single output) are popular in automotive applications due to their extremely wide 4 V to 60 V input voltage range, eliminating the need for a snubber ...
Filter, audio, and RF-communications testing often require a random noise source. Figure 1’s circuit provides an RMS-amplitude regulated noise source with selectable bandwidth. RMS output is 300 mV with a 1 kHz to 5 MHz bandwidth, selectable ...
