This inexpensive FM radio receiver antenna booster uses the BF324 TO92 style pnp transistor in a grounded-base configuration. The circuit may be used as a signal booster with VHF receivers whose front ...

This is a simple 27MHz FM-CB receiver circuit built with TCA440 for listening CB ( citizen’s band ) transmissions with FM (frequency modulation). The selection is made with ceramic filters.

3. The circuit diagram of the dc-dc converter for the FM receiver (5 V/100 mA) includes a "home-made" 220-μH inductor. The input supply voltage (V IN) is connected to pin 6 through ON/OFF ...

Graphene transistors are attractive for many applications but making integrated circuits without degrading their characteristics is proving challenging. Here, the authors demonstrate a radio ...
