An automatically mode-matched MEMS gyroscope with 50 Hz bandwidth
Sonmezoglu, S.; Alper, S.E.; Akın, Tayfun (2012-02-02)
This paper presents the architecture and experimental verification of an automatic mode matching system that uses the phase relationship between the residual quadrature and drive signals in a gyroscope to accomplish and maintain the frequency matching condition. The system also allows controlling the system bandwidth by adjusting the closed loop controller parameters of the sense mode. This study experimentally examines the angle random walk (ARW) and bias instability performances of the fully decoupled MEM...
An Automatically Mode-Matched MEMS Gyroscope With Wide and Tunable Bandwidth
Sonmezoglu, Soner; Alper, Said Emre; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2014-04-01)
This paper presents the architecture and experimental verification of the automatic mode-matching system that uses the phase relationship between the residual quadrature and drive signals in a gyroscope to achieve and maintain matched resonance mode frequencies. The system also allows adjusting the system bandwidth with the aid of the proportional-integral controller parameters of the sense-mode force-feedback controller, independently from the mechanical sensor bandwidth. This paper experimentally examines...
An in-plane high-sensitivity, low-noise micro-g silicon accelerometer with CMOS readout circuitry
Chae, J; Külah, Haluk; Najafi, K (Institute of Electrical and Electronics Engineers (IEEE), 2004-08-01)
A high-sensitivity, low-noise in-plane (lateral) capacitive silicon microaccelerometer utilizing a combined surface and bulk micromachining technology is reported. The accelerometer utilizes a 0.5-mm-thick, 2.4 x 1.0 mm(2) proof-mass and high aspect-ratio vertical polysilicon sensing electrodes fabricated using a trench refill process. The electrodes are separated from the proof-mass by a 1.1-mum sensing gap formed using a sacrificial oxide layer. The measured device sensitivity is 5.6 pF/g. A CMOS readout ...

A 15-40-GHz Frequency Reconfigurable RF MEMS Phase Shifter
Ünlü, Mehmet; Demir, Şimşek; Akın, Tayfun (Institute of Electrical and Electronics Engineers (IEEE), 2013-08-01)
This paper presents a novel frequency reconfigurable phase shifter using the RF microelectromechanical systems (MEMS) technology. The phase shifter is based on the triple-stub circuit topology composed of three stubs that are connected by two transmission lines that are all implemented as distributed MEMS transmission lines. The insertion phase of the circuit is controlled by changing the electrical lengths of the stubs and the connecting transmission lines, while having ideally zero reflection coefficient ...
