Microstrip Open-Loop Resonator With Multispurious Suppression

IEEE Microwave and Wireless Components Letters, 2007
A compact open-loop resonator with multispurious suppression is proposed. When excited symmetrically, the resonator shows two tunable transmission zeros. By adjusting the open-end gap capacitance, one of the zeros is placed near the passband and the other is tuned to collocate with the leading two degenerated higher order resonances, so that the ...

Resonators in Open-Loop Sigma–Delta Modulators

IEEE Transactions on Circuits and Systems I: Regular Papers, 2009
In this paper, we introduce the modulo resonator for use in analog-to-digital open-loop sigma-delta modulators (OLSDMs). The OLSDM presented in this paper is intended for use in high-accuracy (14-bit) high-speed analog-to-digital converters. The modulo resonator is used with a modulo notch filter to insert a zero in the noise transfer function at a ...

An investigation on resonance characteristics of CPS open-loop resonator

APMC 2001. 2001 Asia-Pacific Microwave Conference (Cat. No.01TH8577), 2002
A novel coplanar stripline (CPS) open-loop resonator (OLR) is proposed for maximum miniaturization in uniplanar microwave applications. The effect of variation in the width of longer strips of OLRs formed in two ways (namely, CPS fixed gap and CPS variable gap structures) on their resonance characteristics is discussed.

Open-Loop Resonance-Cancellation Control for a Base-Excited Pendulum

Journal of Vibration and Control, 2001
A new open-loop control strategy applied to a planar pendulum subjected to the most severe com bination of base excitations, horizontal motion at the primary-resonance frequency, and vertical motion at the principal-parametric resonance frequency is developed. The control action is typical of many single-input control systems; the control authority in

Microstrip band rejection filter using open loop resonator

Microwave and Optical Technology Letters, 2008
AbstractDesign of a compact microstrip band reject filter is proposed. The device consists of an Open Loop Rectangular Resonator (OLRR) coupled to a microstrip line. The transmission line has a U‐bend which enhances the coupling with the OLRR element and reduces the size of the filter.

Open-loop experiments of resonator micro-optic gyro

Optoelectronics Letters, 2009
An open-loop resonator micro-optic gyro (R-MOG) with a 6 cm-long waveguide-type ring resonator is set up using the phase modulation spectroscopy technique. In the experiment, according to the test parameters of the resonator, the shot-noise-limited sensitivity is estimated to be 1.07×10−4 rad/s. From the test demodulation signal, the gyro dynamic range

Microstrip low‐pass filter using open loop resonators

Microwave and Optical Technology Letters, 2008
AbstractA compact open loop resonator microstrip low pass filter is modeled. To optimize the performances of the filter, electromagnetic simulation is used to tune the dimensions of proposed prototype. Cascading of open loop resonator provides a very sharp cut off and wide stop band with minimum insertion loss.

A dual‐passband microstrip open‐loop resonator filter

Microwave and Optical Technology Letters, 2005
AbstractIn this paper, a design technique that includes a synthesis procedure and a realization method for a microstrip open‐loop resonator filter with two passbands is described. Transmission zeros of the filter‐transfer function are employed to split a single passband into two passbands, and the filter‐coupling structure used to realize two passbands
