An ultra-fast one-shot frequency doubler is forced by negative feedback to produce a 50% duty cycle square wave output.

Here is a simple frequency doubler circuit that produces a square wave output with a precise 50 percent duty cycle. There are similar circuits in the literature [References 1, 2, 3] which require ...

Graphene transistors are attractive for many applications but making integrated circuits without degrading their characteristics is proving challenging. Here, the authors demonstrate a radio ...

A design of voltage doubler circuit has been studied in context of electromagnetic energy harvesting using 28 nm FD-SOI technology. After analysis of the operating constraints of the circuit, the ...

In use the coupling was adjusted until just before the point at which the circuit began to oscillate, at which point it was in its regenerative high gain and selectivity mode.

Massachusetts Institute of Technology (MIT) has developed a frequency multiplier made from a single grapheme transistor made from material one atom thick. The device can take an incoming signal and ...
