Memcapacitor based CMOS neural amplifier

In this paper, a CMOS neural amplifier based on memcapacitor has been realized. A memcapacitor is a new element based on memristor. A performance comparison between memcapacitor based realization and conventional integrated one has been introduced. The circuits were simulated using 90nm CMOS technology, Vdd = 1.2v, for a total input referred noise of 1.97 μVrms and a total power consumption of 1.28 μW when using memcapacitors for C1 and C2 for a range of frequencies from 0.055 Hz to 6 kHz. The simulation shows a good performance with a smaller size compared to conventional integrated capacitors.
