Abstract: This paper presents a wide-bandwidth, high dynamic range, BiCMOS RF rms detector based on the dynamic translinear principle. A current-domain circuit carries out the main computation, and a ...

We all know of the wired doorbell systems which require wires and suitable outlets for it to work satisfactorily. As the wired doorbell system needs complicated wiring, it requires an experienced ...

A portable Radio Frequency (RF) detector is another useful tool to detect hidden cameras. These devices can pick up the radio frequencies emitted by wireless cameras. Simply scan the room with the ...

In addition, the VCO frequency is connected to a divide by 1, 2, 4, 8, 16, 32, or 64 circuit that allows the user to generate RF output frequencies as low as 62.5 MHz at RF8x. The quality of the clock ...

Robot/metal detector circuit diagram. Source: Interesting Engineering Build the PCB as shown, with the components required. Then insert the Arduino RF Nano, and the DC Motor Driver onto the board.

If you’ve ever browsed through schematics of old vacuum tube radios, [Sebastian]’s JFET-based detector circuit might look ... that would take you down the RF rabbit hole.

RF analyses are well suited for periodic driven and autonomous circuits. Driven circuits are driven by periodic time-varying independent sources and have a periodic solution. The circuit’s steady ...

On August 13, 2021, a divided D.C. Circuit panel granted petitions for ... concerning the FCC's guidelines for radiofrequency (RF) exposure. The court found that the FCC's decision not to revisit ...
