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 ...

Testing FM receivers is not that much different than testing other pieces of audio equipment. Appropriate tests include the big six: level, frequency response, THD+N, phase, interchannel crosstalk ...

The circuit remains a basic component of nearly all modern radio and TV receivers, as well as many types of cellular phones and other communications devices.

How did they get to be so cheap? In part, low-cost technology manufacturing economies have driven down costs, but the real enabler in this case is mixed-signal analog IC technology. Central to this ...

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 ...
