Memristor is a nano device that exhibits unique I-V pinched hysteresis loop with switching mechanism and has ability to remember its last state. These interesting memristor characteristics encourage researchers to understand the new device and develop its potential applications. The problem is memristor has not yet available in current market due to the cost and technical difficulties in fabrication...
In this work, a SPICE memristor model is combined with CMOS element in order to use the memristor resistance to regulate delay of a current starved inverter. Since memristor resistance changes according to supply voltage, the changes of memristor resistance have been studied and demonstrated using a memristor spice model. A pulse signal is supplied to the memristor to control the resistance of the...
Locking speed and operating frequency range of DLL is limited to the delays of its VCDL. Since memristor resistance changes according to external bias, memristor can be used as programmable resistor. In this paper, memristor is applied to VCDL as variable resistor where the memristor resistance regulates total delay of the VCDL. VCDL consists of current starved inverter as the delay unit. A voltage...
A fabricated memristor behavior has been remodel in LT-SPICE and presented in this paper. Memristor SPICE models are important for designers to exhibit memristor behavior since memristor is not yet available in market. Among important parameters in memristor SPICE model is RON, ROFF and TiO2 thickness. This is because different RON and ROFF value results in different switching behavior. In this paper,...
This paper will first review on some applications of newly found passive element, the memristor. Utilizing the beneficial characteristic of memristor where it can remember its last state, more and more improvements on today electronic designs has been proposed. However, it is crucial to observe the behavior of memristor model before applying into circuits, especially when the memristor is coupled...
