Electronically Tunable Fully Integrated Fractional-Order Resonator

An Electronically Tunable Resonator for Noise Control

Many engineering systems create unwanted noise that can be reduced by the careful application of engineering noise controls. When this noise travels down tubes and pipes, a tuned resonator can be used to muffle noise escaping from the tube. The classical examples are automobile exhaust and ventilation system noise. In these cases where a narrow frequency band of noise exists, a traditional engi...

Tunable fractional-order photonic differentiator based on the inverse Raman scattering in a silicon microring resonator.

A novel photonic fractional-order temporal differentiator is proposed based on the inverse Raman scattering (IRS) in the side-coupled silicon microring resonator. By controlling the power of the pump light-wave, the intracavity loss is adjusted and the coupling state of the microring resonator can be changed, so the continuously tunable differentiation order is achieved. The influences of input...

DVCC-based Electronically Tunable First-Order Current-mode Filters

The advent of differential voltage current conveyor(DVCC) has opened up new avenues in analog circuit design. In the present work, a DVCC has been employed to designcurrent-mode first-order continuous-time analog filters. Parameter tunability is achieved by the use of a two-MOSFET electronicresistor which exhibits variation in resistance in accordancewith a control voltage. The proposed circuit...

Electronically Tunable Signal Processing Circuit

This paper presents a voltage mode universal filter using two multi-output operational transconductance amplifier (OTA). Proposed multi-input single output universal filter employs two capacitors only and realizes all the standard second order filtering functions from same configuration. Filter parameters namely pole frequency and quality factor can be tuned independently without affecting each...
