In certain applications, like pH measurement based on electromagnetic field (EMF) changes in an electrochemical reaction, the change in voltage is very small and the voltage range varies with the ...

It is necessary to reduce energy consumption in circuit operations toachieve longer battery life in mobile devices. One new energy reductionscheme is to combine dynamic voltage and frequency scaling ...

The humble NE555 has been around for over five decades now, and while during that time we’ve seen a succession of better and faster versions of the original, the circuits which surround it are pretty ...

Bob Pease had a special love for voltage-to-frequency converter circuitry. I did a vamp on his writing in an article of my own. If you want to measure a voltage in a remote location, it might be ...

Frequency-to-voltage converter chips provide an analog voltage output as a function of the input signal frequency. A frequency-to-voltage converter chip can be accommodated to be used at unipolar, ...

“Facts are stubborn things” (John Adams, et al). I added two 50-ohm outputs to the schematic of my published voltage-to-frequency converter (VFC) circuit (Figure 1). Then, I designed a PCB, purchased ...

See Part 1, Part 2, and Part 3 of this series. The previous FET circuits pertained to voltage-controlled signal amplitude circuits. That is, the input signal’s amplitude can be changed at the output ...
