Nowadays, it is no longer necessary to use discrete components to build oscillators. Instead, many manufacturers provide ready-made voltage-controlled oscillator (VCO) ICs that need only a few ...

This FM transmitter circuit uses four radio frequency stages: a VHF oscillator built around transistor BF494 (T1), a preamplifier built around transistor BF200 (T2), a driver built around transistor ...

Logical circuits have been built from nanosheet stacks of various transistors, which could make electronic devices faster and more compact. Xiong Xiong is in the School of Integrated Circuits and the ...
