The circuit in Figure 1 is suited for inductive sources such as a dynamic microphone, transformer or inductance sensor/pick up. Figure 1 A simple amplifier circuit suited for inductive sources such as ...

A previous Design Idea describes a circuit that uses an astable multivibrator to drive an LED (Reference 1). The circuit in Figure 1 uses a simpler alternative approach. The circuit uses a 2N3904 NPN ...

If you purchased a knock-off FM transmitter and were unhappy with its broadcast range [Thiagohersan] shows how to double the range with a simple transistor amplifier circuit. He also hacked it for ...

THE properties of the amplifier to be described are entirely due to the type of transistor used, and the purpose of this communication is to report on its suitability for the amplification of ...
