Ultra Low-Power Analog Median Filters [PDF]

, 2013
The design and implementation of three analog median filter topologies, whose transistors operate in the deep weak-inversion region, is described. The first topology is a differential pairs array, in which drain currents are driven into two nodes in a ...

Column-row addressing of thermo-optic phase shifters for controlling large silicon photonic circuits [PDF]

, 2020
We demonstrate a time-multiplexed row-column addressing scheme to drive thermo-optic phase shifters in a silicon photonic circuit. By integrating a diode in series with the heater, we can connect $N \times M$ heaters in an matrix topology to $N$ row and $

Real spectra, Anderson localization, and topological phases in one-dimensional quasireciprocal systems

New Journal of Physics, 2022
We introduce the one-dimensional quasireciprocal lattices where the forward hopping amplitudes between nearest neighboring sites { t + t _jR } are chosen to be a random permutation of the backward hopping { t + t _jL } or vice versa.

Topological analysis of qualitative features in electrical circuit theory

, 2005
Several qualitative properties of equilibria in electrical circuits are analyzed in this paper. Specifically, non-singularity, hyperbolicity, and asymptotic stability are addressed in terms of the circuit topology, which is captured through the use of Modified Nodal Analysis (MNA) models.
