This Letter reports the finding of a point-cycle chaotic bursting phenomenon in a simple third-order memristive diode bridge-coupled Sallen-Key lowpass filter (LPF). By parallel coupling a generalised memristor composed of a diode bridge and an inductor into a Sallen-Key LPF a simple third-order memristive chaotic oscillator is established. With the modelling of this oscillator, stability analyses, numerical simulations and hardware experiments are performed, upon which the striking point-cycle chaotic bursting phenomenon is well demonstrated and effectively validated.
