The LM386’s potential as a radio receiver ... SW stations. The schematics show the circuit with a 2N3906 general-purpose PNP transistor, but the 2N2907 and 2N4403 have also been used successfully. In ...

Some 1.5 v LED flasher circuits are available on the internet ... The LED current is approximately 3 mA, so a high brightness LED is recommended. The discrete 3 transistor circuit would need a ...

You probably also have a working knowledge that a germanium diode or a Schottky diode will have a lower forward voltage, and you’ll know in turn that a bipolar transistor will begin to turn on ...

Even in today’s digital, IT-intensive radio plant ... a sound schematic and a working circuit can have many detours and land mines. Lead capacitance and critical parts placement can be particularly ...

and it’s worth seeing the ways that transistor-based circuits differ from tube-based circuits. If you’re interested enough to move on beyond simple radio circuits, though, you can also start ...

The basis of almost everything we discuss here on ExtremeTech is the transistor -- but just ... We are, of course, alluding to circuit schematics. Share on Facebook (opens in a new window) Share ...

However, ensuring these advantages are maintained for integrated circuits ... that in Fig. 3, both the OR and AND gates are composed of pairs of one p-type and one n-type pass transistor connected ...

The last chapter will provide a trip down memory lane for some readers—a sampling of circuits of particular interest in RF history, including the Regency TR-1 transistor radio design and the ...

A new technical paper titled “Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model ... and 100% success with 3-5 additional SPICE simulations.” ...
