On designing linearly tunable high-Q OTA-C filters with low sensitivity
This paper discusses a design approach for a high-Q low-sensitivity OTA-C biquad bandpass section. An optimal relationship is established between transconductances defining the differenceβ - γ in the Q-factor denominator, ...
One-port nonlinear electric circuit for simulating grounding systems under impulse current
(Elsevier B.V., 2016-01-01)
A one-port nonlinear electric circuit to simulate grounding systems behaviors under high impulse currents is presented. The circuit is based on Loboda's and Pochanke's equations, which describe nonlinear behaviors of soil ...
