A CMOS self-biased fully differential amplifier is presented. Due to the self-biasing structure of the amplifier and its associated negative feedback, the amplifier is compensated to achieve low sensitivity to process, supply voltage and temperature (PVT) variations. The output common-mode voltage of the amplifier is adjusted through the same biasing voltages provided by the common-mode feedbac...

Increased production of reactive oxygen species (ROS) in mitochondria underlies major systemic diseases, and this clinical problem stimulates a great scientific interest in the mechanism of ROS generation. However, the mechanism of hypoxia-induced change in ROS production is not fully understood. To mathematically analyze this mechanism in details, taking into consideration all the possible red...

In this paper a current mode very low voltage (LV) (1 V) and low power (LP) (21 μW) differential difference second generation current conveyor (CCII) is presented. The circuit is developed by applying the current sensing technique to a fully balanced version of a differential difference amplifier (DDA) so to design a suitable LV LP integrated version of the so-called differential difference CCI...

the aim of this paper is to study the high order difference scheme for the solution of a fractional partial differential equation (pde) in the electroanalytical chemistry. the space fractional derivative is described in the riemann-liouville sense. in the proposed scheme we discretize the space derivative with a fourth-order compact scheme and use the grunwald- letnikov discretization of the ri...

To increase torque and power conversion of permanent-magnet synchronous motors (PMSMs) at high-speed operation, the dc-link voltage inverter must be fully utilized during steady-state transient operations. This article proposes incorporation a harmonic reference generator (HRG) with pulse clipping (PC) scheme into model predictive control framework to achieve highest output. The HRG calculates ...

We describe a fully differential amplifier for oversampled A/D converter applications. This amplifier employs a single stage telescopic architecture using both N-type and P-type gain-boosting technique with capacitive feedback. This architecture offers extremely high gain, low noise, low power and the need for compensation. But the potential slow-settling problem due to the slow doublet should ...

In this paper, we propose a new method of differential fault analysis of SHA-3 which is based on the differential relations of the algorithm. Employing those differential relations in the fault analysis of SHA-3 gives new features to the proposed attacks, e.g., the high probability of fault detection and the possibility of re-checking initial faults and the possibility to recover internal state...

herein we report a case of primary leiomyosarcoma of testis, which was believed to originate from normal testicular structures.  it contained smooth muscle cells, blood vessels and contractile cells of the seminiferous tubules.  no evidence of tumor spread was found. treatment consisted of orchiectomy with high ligation of the spermatic cord.  the patient received no adjuvant therapy and there ...

conclusions in evaluation of adrenal masses cystic lymphangioma should be considered as a differential diagnosis. introduction adrenal cystic lymphangioma is a rare benign tumor, which is nearly always asymptomatic and incidentally discovered during routine imaging work-ups or investigating other pathologies. case report a 43-year-old female presented hypertension, which during routine work-up ...

iv ACKNOWLEDGEMENTS This thesis would have been impossible without support of many people. I would like to express my sincere gratitude to them, though their invaluable support deserves much more than this short note of appreciation. It is difficult to overstate my gratitude to my advisor Prof. Tamal Mukherjee and Jeyanandh Paramesh. Their enthusiastic and inspirational leadership in research h...
