In this study, six grounded inductance simulator circuits are presented including additional useful features in comparison to previous dual-X current conveyor (DXCCII) based implementations. To demonstrate the performance and usefulness of the presented circuits, one of them is used to construct a fifth order Butterworth highpass filter and a current-mode multifunction filter as application exa...
This paper reports different strategies for electrical dispersion compensation of optical single sideband transmission systems. We investigate and compare the mitigation of the chromatic dispersion impairment using dispersive microstrip lines, Butterworth filters, and hybrid schemes employing an adaptive filter. Simulation results are presented at 10 Gbit/s, proving transmission over 600km of d...
This paper sets out the theoretical foundations for continuous-time signal extraction in econometrics. Continuous-time modeling gives an effective strategy for treating stock and flow data, irregularly spaced data, and changing frequency of observation. We rigorously derive the optimal continuous-lag filter when the signal component is nonstationary, and provide several illustrations, including...

The design of grating-assisted, channel waveguide, codirectional couplers is demonstrated using the Gel’fand-Levitan-Marchenko inverse scattering method. Weighted coupling coefficients are computed from rational function expressions for the desired wavelength response. Approximate formulas are derived which relate the waveguide and grating geometries to the computed coupling coefficients. The t...
The design, fabrication, and measurement of planar, passive Bragg grating-based transmission filters is presented. We combine interferometric lithography, spatial-phase-locked electron-beam lithography, x-ray nanolithography, and optical lithography with silica-on-silicon waveguiding substrates to define rib waveguides and grating patterns that have multiple quarter-wave shifts along the gratin...
A highly linear 600 MHz centre frequency, 500 MHz bandwidth 6 order Butterworth bandpass filter using a LeapFrog Gm-C topology is designed. Fully differential inverter based Operational Transconductance Amplifier (OTA) with common-mode feedback (CMFB) and common-mode feed forward (CMFF) circuit is used in the design. Cadence tool has been used on IHP SiGe BiCMOS 0.25 μm node. The filter consume...
