The circuit can be culled from the MCP2120 developer`s kit user`s guide. It is on page 51 of document DS51246A. If you don`t want to use an integrated transceiver, there is a circuit for you to build your own with a seperate ir led and detector. Make sure....

Many designers opinionate that NFB loop controlled amplifiers are inferior because they degrade the sound, and yet I wonder what it is that these individuals think they actually listen to ? The fact is that most vinyl waveforms and CD pits, as pressed into....

The tuned circuit consists of a variable capacitor and fixed air spaced coil. For the coil, I wound between 10 and 20 turns of wire on an empty tube of around 1.5 inches diameter. The turns were spaced so that the overall length was around 3 inches. The....

Two conventional amplifier stages built with SF215 transistors are linked by ceramic 10.7MHz IF filters, and followed by an FM demodulator built with a TBA120T i.c. Straight from the databook. Output goes via a 100k log potmeter (not shown) to the audio....

This circuit relies upon the extra high input impedance of a FET, and also demonstrates the gate terminals sensitivity to changes in voltage. The gate terminal here is left open circuit, connected only to the "probe" this being just a few inches of bare....

One of the most interesting projects to work with is that of a synthesizer that can accurately gnerate desired frequencies. This synthesizer uses just three CMOS chips and one PNP transistor. It is a fact that the transistor may be the hardest component to....
