Optimal allocation of local feedback in multistage amplifiers via geometric programming
Amplifiers analog circuits circuit optimization design automation geometric programming sensitivity
2015/8/11
We consider the problem of optimally allocating local feedback to the stages of a multistage amplifier. The local feedback gains affect many performance indices for the overall amplifier, such as band...
Variance and kurtosis-based characterization of resonances in stochastic transmission lines: local versus global random geometries
Variance and kurtosis-based characterization stochastic transmission lines global random geometries
2010/1/11
A stochastic method is proposed to characterize electromagnetic couplings involving geometrically perturbed transmission lines. A combined exploitation of suitably defined statistical tools is present...

An Analytical Study on the Local Electronic Density of States of the Valence Bands in Amorphous Silicon Carbide
Local valence band density of states amorphous silicon carbide hybrid orbitals
2010/12/9
A formulation for the energy-averaged local valence band density of states of amorphous silicon carbide is derived. To this end, sp3-type hybrid orbitals are employed.
