The time-domain response of coupled-resonator filters with applications to tuning [PDF]

open access: yes, 2004
This thesis develops a new theory of tuning filters based on the time-domain response of the filter. These methods are shown to work very well for all-pole coupledresonator filters in particular, and may be applied to automated tuning of filters ...

A Temperature-Hardened Sensor Interface with a 12-Bit Digital Output Using a Novel Pulse Width Modulation Technique

open access: yesSensors, 2018
A fully integrated sensor interface for a wide operational temperature range is presented. It translates the sensor signal into a pulse width modulated (PWM) signal that is then converted into a 12-bit digital output.

Time-Domain Circuit Modelling for Hybrid Supercapacitors

open access: yesEnergies, 2021
Classic circuit modeling for supercapacitors is limited in representing the strongly non-linear behavior of the hybrid supercapacitor technology. In this work, two novel modeling techniques suitable to represent the time-domain electrical behavior of a ...

A Low-Complexity Time-Domain Method for a Fast and Accurate Measurement of Q-Factor and Resonant Frequency of RF and Microwave Resonators

open access: yesIEEE Access, 2021
A new time-domain technique for an accurate and fast measurement of the resonant frequency and $Q$ -factor of resonators is presented. In this technique, the phase slope with respect to frequency of a resonator is characterized and used to specify its $

Time domain reflectometry applied to MMIC passive component modeling [PDF]

open access: yes, 1989
The time domain facilities of a network analyzer, combined with the tools of network synthesis, were recently used for experimental modeling of discontinuities in an S-parameter measurement set, so as to allow the instrument calibration directly to the ...
