Transistor radio circuit schematic The demodulated signal comes out from the collector of T1. The signal is then filtered by C3 so that only the audio signal will be amplified by T2. The amplified ...

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 ...

The research opens a rational pathway to scalable fabrication of high-speed, self-aligned graphene transistors and functional circuits and it demonstrates for the first time a graphene transistor ...
