A multi-step electromechanical Sigma Delta converter for micro-g capacitive accelerometers Külah, Haluk; Yazdi, N; Najafi, K (2003-01-01) A multi-step electromechanical /spl Sigma//spl Delta/ modulator for /spl mu/g accelerometers is described. A two-element sensor array is used in two /spl Sigma//spl Delta/ loops and resolution improves by >2x compared to a conventional 2nd-order /spl Sigma//spl Delta/ modulator. This CMOS chip operates at 1 MHz and provides 0.2-1.2V/pF sensitivity, <20aF resolution, >120dB dynamic range, and dissipates <12mW
A 180 nm Self-Powered Rectifier Circuit for Electromagnetic Energy Harvesters Ulusan, Hasan; Zorlu, Ozge; Külah, Haluk; Muhtaroglu, Ali (2013-12-18) This paper presents a new self-powered low voltage rectifier implementation for vibration-based electromagnetic (EM) energy harvesters. The proposed circuit is an improved version of the previously reported rectifier, which was designed in TSMC 90 nm CMOS technology. The circuit is designed in lower cost UMC 180 nm CMOS technology, and uses a passive AC/DC quadrupler structure to supply the external power of the utilized active components. Simulation results show that the maximum power conversion efficiency...
A self-powered integrated interface circuit for low power piezoelectric energy harvesters Chamanian, S.; Zorlu, O.; Külah, Haluk; Muhtaroglu, A. (2013-12-18) This paper presents a CMOS integrated interface circuit for piezoelectric energy harvesters (PEH). A fully self-powered circuit, based on Synchronous Electric Charge extraction (SECE) technique, is implemented for non-resonant piezoelectric harvesters generating low power, in 10s to 100s mu W range. The circuit is realized in standard 180 nm UMC CMOS technology. A switch control circuit is designed and optimized to extract maximum power independently from excitation changes of the PEH. The total power loss ...
