Resistor‚ Capacitor and Inductor make up some of the basic elements in any circuit system. Memristor or a memory resistor is described as a resistor which can store data. This characteristic of the memristor is the reason it is most sought after for use in memory related systems. [6] The concept of memristors was first theorized by Prof. Leon. O. Chua in 1971. It wasn’t until Stanley Williams invented the crossbar latch in 2008 that the scientists realized the memristor could be made possible. It

of a VCO is the 566 IC unit‚ which contains circuitry to generate both squarewave and triangular-wave signals whose frequency is set by an external resistor and capacitor and then varied by an applied dc voltage. Figure (1) shows that the 566 contains current sources to charge and discharge an external capacitor C1 at a rate set by external resistor R1 and the control dc input voltage. A Schmitttrigger circuit is used to switch the current sources between charging and discharging the capacitor‚ and

Shown here is a schematic diagram for a real inverter circuit‚ complete with all necessary components for efficient and reliable operation: This circuit is composed exclusively of resistors and bipolar transistors. Bear in mind that other circuit designs are capable of performing the NOT gate function‚ including designs substituting field-effect transistors for bipolar (discussed later in this chapter). Let’s analyze this circuit

composed of at least one resistor and at least one capacitor. A capacitor is composed of two plates with either air or an insulator also known as a dielectric between the plates. We do not want the plates to be touching‚ because then we would only have a conductor. The insulator between the plates is also known as the dialectic‚ which affect how the capacitor will store charge. In an RC circuit‚ voltage will flow from the battery to the capacitor and through the resistor. When the capacitor is charging
