A coupled memcapacitor emulator based relaxation oscillator
Tremendous efforts have been put into dissecting the inherent characteristics and potential applications of Memcapacitor (MC), which possesses unique abilities of storing both information and energy [1]. Recently, coupling is disclosed as the third relation beyond series and parallel connections of memristive circuits in [2], of which the mechanical dynamic coupling of MCs is taken into account for illustration purpose. Coupled MCs could provide us more opportunities for developing new electronic devices with unique functions. However, very few works currently focus on the practical implementation of coupled MC emulators and its possible application in electronic circuits. In this letter, a practical emulator of coupled MC is newly proposed and then used for structuring Relaxation Oscillators (ROs), of which the period and duty cycle of output oscillating signal can be purposefully controlled in virtue of the coupling action.
