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 CMOS Based Current-to-Frequency Converter for Current Output Analog Accelerometers Nuzumlali, Omer Lutfi; Eren, Murat; Külah, Haluk (2013-04-25) This paper presents a novel design of a high resolution CMOS based current to frequency converter (CFC), also known as integrating analog to digital converter (IADC), especially for current output navigation grade accelerometers. Different from the traditional design, positive and negative input currents are separated from each other to eliminate the error due to both comparator offset voltages and mismatch in the value of integrating capacitor. Also, the output current of the accelerometer is directly inte...
A Parabolic Band Hysteresis Current Controller for Doubly Fed Induction Generators Hamadi, Emad; Mortazavi, S. S. (2011-09-10) A parabolic band hysteresis current controller (PBHCC) for DFIG is proposed in this paper to control the switching frequency variations in rotor side converter (RSC). A generalized online technique is used to determine the set of unique parabolic boundary for any operation speed. The PIHICC then utilized to regulate the current in RSC. In contrast to PI controller, PBHCC shows a very good transient behaviour. Beside that, the steady state performance is improved by reducing the switching frequency considera...
A CMOS High Frequency Pulse Width Modulation Integrated Circuit Sahin, Osman Ulas; Kocer, Fatih (2016-08-05) In this work, a high frequency pulse width modulation (PWM) integrated circuit (IC) designed and implemented in a commercial 0.35 mu m CMOS process is presented. Based on natural sampling method, the proposed PWM IC can generate both a PWM signal and its inverse for arbitrary frequencies up to 5 MHz. The PWM frequency can he adjusted via an external clock and an off-chip capacitor. The duty cycle of the PWM signal can be linearly varied from 5% to 95% by changing the input signal. Thanks to its analog trian...
A DSP based active noise controller for headphones Tokatli, A; Çiloğlu, Tolga (2004-04-30) In this article, a battery powered, TMS320VC5416 DSP controlled active noise control system is described and test results are presented. The whole system hardware and software has been designed and implemented in our lab.
A Near-State PWM Method With Reduced Switching Losses and Reduced Common-Mode Voltage for Three-Phase Voltage Source Inverters Uen, Emre; Hava, Ahmet Masum (2009-03-01) The near-state pulsewidth modulation (NSPWM) method, which reduces the common-mode voltage/current, is proposed for three-phase pulsewidth modulation (PWM) inverter drives. The method is described, its optimal voltage vectors are found, and the sequence that these vectors are applied is determined. Its voltage linearity and de bus and ac output PWM current ripple characteristics are studied. Its output line-to-line voltage pattern is carefully studied with regard to switching transients that may cause overv...
