The transistor and the PWM-switch, the core circuit of power converters, have interesting analogs. Both have three terminals, hence three configurations. They are active devices, and each has a key ...

This project demonstrates how to build a simple latching power switch circuit using an NPN transistor and a pushbutton, powered by a 9V battery. When the pushbutton is pressed, the transistor ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

Abstract: In this paper some characteristics of switch circuits using junction transistors are analyzed. The switch properties result from the large changes in small-signal admittance of one junction ...

Transistors, the tiny switches that flip on and off inside computer chips, have long been the domain of electricity. But scientists are beginning to develop chip components that run on light. Last ...

This video explains how transistors work as switches and amplifiers in electronic circuits. Transistors control the flow of ...

Among semiconductors, the muting transistor and its audio application is perhaps the most obscure and poorly understood of all. There is extremely little information on this subject available on the ...

Ever wondered how a solar-powered lamp powers an LED with just a single 1.2 V cell? A closer look reveals a clever single-transistor voltage converter circuit. Curious how a solar-powered lamp powers ...

Abstract: Fine-grained sleep transistor circuits are demonstrated with 0.12μm 16 b MAC (multiply-accumulate unit). Standby power is reduced by a factor of 5500 at 85°C with speed reduction of 5%.

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
