A DC motor can be switched ON and OFF using this amplifier circuit while being able to regulate its spinning speed with a PWM source generator. The circuit is using the pin 9, 10, and 11 from the ...
Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...
Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...
