The LM48824`s Stereo Headphone Amplifier (Class G architecture ) increases audio (MP3, mobile TV, etc. ) playback time with its adaptive power supply approach that enables very low supply rails, which doubles the power-efficiency compared to typical Class AB....

Stationary - MOPLL & Silicon Tuner TUA6020 2 Band TV Tuner Mixer-Oscillator-PLL with balanced IF-Amplifier The TUA6020 device combines a digitally programmable Phase locked loop (PLL), with a mixer-oscillator block including two balanced mixers and oscilla-....

This LED flasher circuit is a classic two transistor flip flop. This flasher circuit is very popular and it`s usually the first circuit to build when starting electronic circuit building hobby. Here is the schematic diagram of the famous LED flasher circuit:....

There are plans to make it 1Gsps in the future, using interleaved ADCs and staggered clock, but that`s beyond me at the moment, so the first iteration will only have 100Msps (fastest from single ADC). The part I`m most unsure about is the analog front end,....

Using TDA7262 integrated circuit manufactured by ST Microelectronics can be designed a very simple stereo audio amplifier electronic project which can provide a maximum output power of 20 watts per channel. TDA7262 is an ( class AB ) dual Hi-Fi Audio power....

Here`s some schematics and information that can be hard to find elsewhere. If you have some schematics that you think belongs among these, please do not hesitate to contact me. I hope to be able to extend this little collection with time, so check back for....

For many years, the Q meter has been an essential piece of equipment for laboratories engaged in the testing of radio frequency circuits. In modem laboratories, the Q meter has been largely replaced by more exotic (and more expensive) impedance measuring....

As some of you know, the Traynor YBA-1 is a very close derivative of the classic Bassman/JTM-45 circuit. I recently picked up a spectacularly clean `67 copy that was all original with the exception of a rather "crappy" fully reversible master volume mod and....

In this circuit, a 74HC14 hex Schmitt trigger inverter is used as a square wave oscillator to drive a small signal transistor in a class C amplifier configuration. The oscillator frequency can be either fixed by a crystal or made adjustable (VFO) with a....

30W Class AB power amplifier circuit diagram using power transistor. Set the above amplifier up by adjust the variable resistor R1 to maximum and R12 to zero. After this set up is done, the activate / turn on the amplifier. Adjust the R1 so that the measured....

The open-loop concept of oscillator design is often met with considerable skepticism by engineers familiar with classic oscillator terminology. For comfort consider Figure 2-4A where the oscillator cascade is drawn with only the RF components. Next, the....
