The magnetic field energy becomes a maximum when electric field energy is zero. Hartley Oscillator is a device that generates oscillatory output sinusoidal. It consists of an amplifier linked to an oscillatory circuit, also called LC circuit or tank circuit. The function of tank circuit is to tune a certain frequency.
LC oscillators are designed to operate in the radio-frequency range. Its inductance will be in micro Henries. However they can also be designed to produce oscillations in the low audio-frequency range. But for the low-frequency operation, the inductors used will be very large in value, i. The circuit oscillates when the components are suitably selected to satisfy the Barkhausen criteria.
In Hartley oscillator the feedback voltage is across L 2 and output voltage is across L 1. Feedback ratio. For faithful amplification, a transistor amplifier must satisfy three basic conditions, namely: Fulfilment of these conditions is known as transistor biasing. One method of obtaining transistor biasing is by potential divider arrangement.
The circuit consists of a potential divider arrangement. R 1 and R 2 form a potential divider across Vcc.
The voltage drop V R2 across R 2 forward-biases the emitter whereas Vcc supply reverse biases the collector.
