This paper presents a floating memristor circuit that can operate at high frequencies,which consists of a cross-coupled operational transconductance amplifier(OTA),a floating current source,and a ground capacitor with a grounding resistor.The memristor circuit improves the operating frequency range by using an OTA with cross-coupling;the floating memristor realizes switching between two states,incremental and decremental,by flipping the input port.The proposed circuit is based on the SMIC 180 nm CMOS process,and is powered by±0.9 V dual supplies.The maximum operating frequency of the memristor can reach 100 MHz with a power consumption of 0.496 m W.
