Hartley Oscillator Circuit Diagram. An npn transistor connected in a common emitter configuration works as the active device in amplifier stage. The circuit diagram of a typical hartley oscillator is shown in the figure below.
Here simple hartley oscillator circuit designed to provide wide range of sinusoidal output. The circuit diagram of a hartley oscillator is shown in figure below. Ce is the emitter by pass capacitors which by passes the amplified ac signals.
Let us first understand the use of these elements in the circuit.
The circuit diagram of a typical hartley oscillator is shown in the figure below. Here simple hartley oscillator circuit designed to provide wide range of sinusoidal output. In the circuit diagram resistors r1 and r2 give a potential divider bias for the transistor q1. The circuit diagram of a hartley oscillator is shown in figure below.
