Hartley oscillator lab manual

As shown in Figure below, in common emitter configuration NPN transistor connected serves as an active device in amplifier stage, R1 and R2 are biasing resistors, RFC is the radio frequency choke which provides the isolation between AC and DC operation, capacitors Cc1 & Cc2 are the coupling capacitors. Hartley Oscillator circuit Diagram Because in Fig. 2.1.6 (and Fig. 2.1.1) the top of L1 is connected to +Vcc, it is, as far as AC signals are concerned, connected to ground via the very low impedance of C5. Therefore waveform X across L1, and waveform Y across the whole circuit are in phase. As a common base amplifier is being used, the collector and emitter signals are also in phase, and the tank circuit is therefore providing positive feedback. In other Hartley designs, using common emitter amplifiers for example, similar tank circuits are used but with different connections, so that the feedback signal is always in phase with the input signal, therefore providing the necessary positive feedback.
