Memristor-Based Phase-Lead Controller Circuit Design

Memristor predicted and described by L. O. Chua is a new electrical element. Memristor with variable resistance which changes automatically as its voltage changing can be used as a tunable parameter in control systems. Phase-lead controller is widely used in industrial process control applications. The conventional method for adjusting phase-lead controller parameters is based on the “trial and...

A Voltage Mode Memristor Bridge Synaptic Circuit with Memristor Emulators

A memristor bridge neural circuit which is able to perform signed synaptic weighting was proposed in our previous study, where the synaptic operation was verified via software simulation of the mathematical model of the HP memristor. This study is an extension of the previous work advancing toward the circuit implementation where the architecture of the memristor bridge synapse is built with me...

High-speed interface circuit for differential capacitance transducers

A high-speed capacitance difference-to-sum ratio measurement circuit is presented for differential capacitance transducers. It consists of a switched-capacitor input stage, two sample-and-hold (S/H) circuits followed by voltage-to-current (V/I) converters, and a current-ratio-controlled relaxation oscillator. This circuit offers a square-wave output whose oscillation period is directly proporti...
