Shrinking reserves of natural resources as well as incisive environmental pollution oblige humanity to rethink its generally favored propulsion concept: in the last decade electro-mobility as a refurbished technology gained greater significance once more. Due to political course setting, many German cities are testing Electric Vehicles (EV) especially in public bus transport. To get to the bottom...
Because of the dynamic, nonlinear and multi-parameter characteristic of the refrigeration system, it is difficult to keep the system operating under the optimal state. Based on the improved back-propagation (BP) of artificial neural network (ANN) with the momentum factor, the program to predict the performance of refrigeration system at part-load condition is established by Visual C++ 6.0. The training...
A high-performance CMOS band-gap reference (BGR) is designed in this paper. The proposed circuit employs the current-mode architecture optimized for low supply voltage applications. The key portion of the circuit employs the Brokaw BGR architecture, in which a three-stage operational amplifier is adopted to get high PSRR and only first-order temperature compensation technology is employed to get a...
The lifetime of integrated chip tends to decrease more and more with technology scaling. To check if a design is robust, in this paper we present RTME (real time MTTF evaluation), a simulation framework that enables the evaluation of reliability at higher level of abstraction layer. Using the output of RTME, we are able to distinguish the effect of different benchmarks on different blocks of the processor.
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
Advances in micromachining technology can facilitate the integration of SAW (Surface Acoustic Wave) devices and CMOS circuitry on IC scale substrate for Monolithic fabrication. The optimal design and performance of these filters can be reached by using new Smart materials. The key component in the structure of the SAW device is the piezoelectric materials used which depends mainly on some important...
