Schematic visualization is important for analog circuit designers to quickly recognize the structures and functions of transistor-level circuit netlists. However, most of the original analog design or ...

Superheterodyne AM Receiver Circuit Now, we know the basic functionality working of a Superheterodyne Receiver, let’s take a look at a typical circuit diagram of Superheterodyne Receiver. The below ...

NPN Transistor Switching Circuit Before starting with the circuit diagram, you should know the concept of NPN transistor as a switch. In an NPN transistor, Current starts flowing from collector to ...

FM Receiver Circuit Explanation Here’s a simple FM receiver circuit with minimum components for local FM reception. Transistor BF495 (T2), together with a 10k resistor (R1), coil L, 22pF variable ...

The schematic diagram shows an audio stage with a common-collector circuit. This does not damp the tuned circuit, but instead actually increases its response. This yields good sensitivity and ...

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 ...
