The feasibility and quality of Memory-based Physical Unclonable Functions (MemPUFs) based on emerging Non-Volatile Memory (eNVM) technologies (Spin-Transfer Torque Magnetic Random Access Memory, Phase Change RAM, and Resistive RAM) are studied in this paper. MemPUFs using the three technologies were evaluated in terms of reliability, uniqueness and randomness using different sensing modes and under...
This paper presents an approach to realize very high value of resistance through well to source connected PMOS devices working in weak inversion. The derivations of formulas were based on the concept of EKV equation at weak inversion. Analysis has been done to correlate conductance with the biasing voltage. The developed approach has been applied to the design of high resistance circuit for Piezo-electric...
This paper presents an innovative conditioning and read-out interface for resistive MEMS sensor named ldquoactive-bridgerdquo. Different implementations of the proposed structure were evaluated by electrical simulations, using a 0.35mum AMS technology. The results demonstrate a significant power consumption reduction for a given SNR or a greater SNR for a given current consumption.
In this paper, design and characterization of a 18 V switched-capacitor CMOS interface circuit for the closed-loop operation of a capacitive accelerometer is presented. The pendulous silicon accelerometer operates in atmosphere pressure and is designed for non-peaking (low-Q) response with a sensitivity of 0.5 pF/g without vacuum packaging. Test results shows that a full scale acceleration of plusmn15...
We studied electrical noise of gold nanoparticle chemical sensors with the intent of improving their limit of detection. All the sensors exhibit 1/f-type noise at low frequencies. The magnitude of the noise is found to be strongly dependent on the thickness of the films. The sensors containing a single monolayer of nanoparticles had the highest resistance and the worst noise performance. By making...
Linear motion and out-of-focus blur often coexist in a surveillance system, which degrade the quality of acquired images and thus complicate the task of object recognition and event detection. In this work, we present a point spread function-based (PSF-based) approach considering fundamental characteristics of linear motion and out-of-focus blur based on geometric optics to restore coexisting motion...
This paper is concerned with the design and simulation of a pulse width modulation (PWM) rectifier for three-phase Permanent Magnetic motor drive. Based on the mathematical model of PWM rectifier, the dual-close-loop engineering design with decoupled feed-forward control is applied in the 3-phase voltage source rectifier. The objective to be reached is to realize unity power factor at the input ac...
In deep submicron era, to prevent larger amount of SRAM from more frequently encountered overheating problems and react accordingly for each possible hotspots, multiple ideal run-time temperature sensors must be closely located and response rapidly to secure system reliability while maintaining core frequency. This paper presented a method to extract run-time temperature information from multiple...
The real time monitoring and control of resistance spot welds is a problem of critical importance in automotive and many other manufacturing industries. However, till this date, there are no reliable, low-cost, non-destructive techniques for predicting the size and strength of the weld nuggets in real time. This paper investigates the usage of voltage, current, and force data for the above tasks....
