Circuits & Schematics High Voltage

Applications ranging from frequency counting and synthesis to sensor signal conditioning require conversion of RF signals to digital-logic levels. In such situations, designers typically use a high-speed voltage comparator to perform the ...

Some transducers for portable or automotive applications need accurately regulated, high-voltage bias and draw little current. To produce such high voltages from a low battery voltage, designers typically use switch-mode dc/dc converters generally, ...

Jui-I Tsai, Woei-Wu Pai, Feng-Chang Hsu, Po-Jui Chen, Ching-Cheng Teng, Tai-Shan Liao EDN Most laboratories and industrial environments have many kinds of electrical-noise sources at all frequencies from heavy machinery, instruments, power ...

Gavin Watkins EDN A recent project evaluated the feasibility of a dynamic load modulation (DLM) RF power amplifier for 5G. DLM amplifiers typically use high-voltage varactor diodes in their output network, which need to be driven by high-speed ...

EDN You sometimes need a current source for supply voltages as high as 1000 V or more. This current source can be useful for ripple-voltage reduction when the current source’s high-impedance node feeds an electrolytic capacitor to effectively ...

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 ...

Gheorghe Plasoianu EDN Designing a high-voltage regulator can pose difficulties associated with component stress, reliability, and costs. This Design Idea offers a solution: a simple unregulated high-voltage supply in series with a low-voltage ...

George Qian, Michael Wu, Analog Devices Design Note 1047 Introduction Isolated flyback converters are used in automotive, industrial, medical and telecom applications where the power supply must be reliable, easy-to-use, high voltage and isolated, ...

Bipin Duggal EDN Piezoelectric tubular positioners that drive manipulators in scanning tunneling microscopes require high-voltage, low-current drive circuits. The circuit in Figure 1 can drive high-resistance, low-capacitance piezoelectric loads at ...

Steven Galecki Electronic Design This circuit automatically attenuates a high voltage by known factors so that it matches the ADC input range for best converter resolution. It's a common challenge to measure voltages that exceed the operating ...
