There are many different types of oscillator circuits, the majority of which use positive feedback.
The phase-shift oscillator gets its name from the phase-shift network used in its design, which introduces a phase shift in the feedback path of the circuit. This phase shift is necessary for maintaining oscillations in the circuit.
it is the circuit that is responsible for producing oscillation.In hartley it is two inductors connected in series and a capacitor parallel to this series connection.Without tank oscillator tends to act as as an amplifier.
The Franklin oscillator is a type of electronic oscillator circuit that generates a sinusoidal waveform at a specific frequency. It typically consists of a feedback network with capacitors and inductors that determine the frequency of oscillation. The oscillator is named after its inventor, William R. Franklin. The Franklin oscillator is commonly used in radio frequency (RF) applications due to its stability and accuracy in generating precise frequencies.
A Wien-bridge oscillator generates a sinusoidal waveform using an op-amp and a feedback network with both resistors and capacitors, while a phase-shift oscillator uses an RC network to introduce phase shifts in the feedback path to generate oscillations. Wien-bridge oscillators are typically used for audio frequency applications, whereas phase-shift oscillators are commonly used for higher frequency applications.
In an RC phase shift oscillator, one emitter follower stage is typically used to provide the required phase shift. In a Wien bridge oscillator, two emitter followers are used to achieve the required feedback and oscillation.

The oscillator which is blocked by using transformer is called a blocking oscillator. Generally, the primary is given to the base and secondary is given to the collector of the transistor used in the oscillator circuit.
Oscillators are connected externally with the microcontroller to provide high frequency signal to the oscillator circuit in the microcontroller. The oscillator circuit provides the clock signal to the micro controller. Usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.
Positive feedback is used in oscillators to keep them running or oscillating. An oscillator is basically an amplifier which has a feedback path from the output back to the input. This permits a portion of the output signal to get back to the input to "keep things going" in stage - to keep things oscillating. The feedback must be positive so that it will "contribute" to the stage being able to keep oscillating. If the feedback was negative, it would serve to damp the oscillation and to "kill" the oscillator.
