Comprised of two precision op amps (MAX4236), a voltage reference (MAX6143), a NAND gate, and associated components, this DC-voltage detector circuit asserts a digital output signal when the input is ...

The present IP is a VCC Detector (VDT) circuit, which prevents the possibilities of causing Flash writing failure or internal operation failure by uns ...

A function often needed in industrial and scientific applications is detecting the presence (or absence) of dc voltages in such components as safety interlocks and automatic sequencers. To detect the ...

This design idea showcases a circuit that detects RF “bugs,” such as hidden wireless cameras, eavesdropping microphones, and other spying devices that emit RF frequencies in the 100MHz to 3000MHz ...

[Dino] is back with another installment of his Hack a Week series, and in this episode he is taking on what he promises will be the last transistor-based project – at least for a little while. In the ...
