Abstract: Asimple circuit consisting of a comparator and an exclusive-ORgate is sufficient to double the frequency of a reference signal. The versatile phase-locked loop (PLL) allows multiplication of a reference frequency with an operating frequency that ranges from "DCto daylight." A PLL is o...
We use it to produce the high current pulse to thesimple double voltage circuit. Which they work with the capacitors and diodes. This does not need to use any coil. So, easy and cheap. And, Imagine when you finish this DC converter job. You are bored. You can rebuild it into a nice...
However, since the output is a DC, this can be diode application circuit can be used only for appliances that can work with AC and DC both, for example, electric shavers, LED lamps, heaters, electric motors, electric iron, soldering iron etc. Air Ionizer The above voltage doubler when ext...

Supply inputs to pins 14 and 7 are not shown in the drawings for simplicity sake, but you are advised not to forget to connect these pins, or else the circuit would simply fail to work! All the circuits work using a 4.5 V or 6 V DC supply however the typical voltage can be 5 vol...
This proposed neon globe flasher circuit circuit makes it possible for neon bulbs to be powered through a low voltage dc supply. The voltage necessary to fire up the neon tube is achieved through an normal step down transformer 240-6.3V connected in the in the reverse order. ...
The rectified DC from the diodes provide the necessary biasing to the Q2 transistor base, so that it turns ON illuminating the attached LED. The switched ON LED confirms that the crystal under test is a good crystal, and the circuit is correctly oscillating with the help of the crystal. ...
