A simple stereo tv decoder circuit build with MC1310P. Transistor Q1 is an audio amplifier and U1 is used as a 31.5KHz subcarrier which is similar to 38KHz FM MPX. Pilot frequency is 15.734KHz. Stereo ...

The transistors were already at the limit of what steady hands and tiny tweezers could handle. So, scientists wanted to make a whole circuit -- the transistors, the wires, everything else they ...

Nature Scientific Reports – Scalable circuits of organic logic and memory are realized using all-additive printing processes. A 3-bit organic complementary decoder is fabricated and used to read and ...

In multiple-output power supplies in which a single supply powers circuitry of vastly different current draws, two perplexing steps are sensing the current that each output draws and deactivating the ...

Field-effect transistors based on carbon nanotubes have been shown to be faster and less energy consuming than their silicon counterparts. However, ensuring these advantages are maintained for ...

[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out… ...

These switches need to be "ON" (binary state "1") to forward-bias the transistor, energize the relay (used in normally open mode), and activate the user's solenoid system to open the lock.
