A new approach to denoise chaotic signals based on ensemble empirical mode decomposition (EEMD) is proposed. The EEMD technique is first used to decompose the noisy chaotic signal into the so-called intrinsic mode functions (IMFs). A criterion is proposed to determine which modes are used to reconstruct the denoised signal. Computer simulations are used to demonstrate the effect of the method. The...
For low-light-level imaging, the performance of a CMOS image sensor (CIS) is usually limited by the temporal readout noise (TRN) generated from its analog readout circuit chain. Although a sub-electron TRN level can be achieved with a high-gain pixel-level amplifier, the pixel uniformity is highly impaired up to a few percent by its open-loop amplifier structure [1]. The TRN can be suppressed without...
An intelligent control of the automated highway system for the guidance of four wheeled vehicles is proposed. The control objective is to find one control law that can automatically guide the new-generation smart vehicles when driving in the highway under the effects of uncertain disturbance as wind gust, etc. We successfully propose one control law for designing the intelligent control of four wheeled...
This paper presents a CMOS image sensor (CIS) with pinned-photodiode 5T active pixels which use an in-pixel buried channel source follower (BSF) with an optimized row selector (RS). According to our previous work [1][2], using in-pixel BSFs with optimized RS can achieve significant pixel dark random noise reduction, i.e. 50% reduction, specially for random telegraph signal (RTS) noise, and an increase...

There are, in practice, so many control systems possesses this kind of special feature, e.g., ballistic missile's maneuver couples with wind gusts, acceleration signal measured by accelerometers couples with the external and internal noises, and so on. Generally, the input signal u(k) is always assumed as an exactly known variable and never corrupted with noise; hence one is capable of dealing with...
<para> This paper presents a CMOS imager sensor with pinned-photodiode 4T active pixels which use in-pixel buried-channel source followers (SFs) and optimized row selectors. The test sensor has been fabricated in a 0.18- CMOS process. The sensor characterization was carried out successfully, and the results show that, compared with a regular imager with the standard nMOS transistor...
An advanced elimination algorithm based on the dynamic PID control concept for treating drift rate effects of MEMS-Based inertial devices, such as accelerometer and gyroscope is proposed in this investigation. Effects of drift rates of inertial devices strongly influence the performance of the relative motion sensing products that are designed by MEMS-based inertial devices, e.g., small regions of...
