A type of oscillator consisting of a transistor with common-emitter connection and a parallel resonant circuit between the emitter and collector (see diagram). Ignoring the resistance of the coil the resonant frequency, , is given by
Hartley oscillators may also be crystal-controlled (see piezoelectric oscillator, Fig. d).
