Improved Slater approximation to SIC–OEP

signal specific successive approximation analog to digital converter

چکیده: در میان انواع متفاوتی از مبدل های آنالوگ به دیجیتال که تا کنون معرفی شده اند، مبدل های آنالوگ به دیجیتال تقاریب متوالی(sar ) به علت سادگی ساختار و همچنین توان مصرفی کم، همواره یکی از پرکاربرد ترین مبدل های آنالوگ به دیحیتال در کاربرد های بایومدیکال بوده اند. به همین دلیل تاکنون روش های متعددی برای کاهش هرچه بیشتر توان مصرفی در این مبدل ها ارائه شده است که در اکثر آنها توجهی به مشخصات سی...

Improved Gaussian Approximation

In a recently developed approximation technique [1] for quantum field theory the standard one-loop result is used as a seed for a recursive formula that gives a sequence of improved Gaussian approximations for the generating functional. In this paper we work with the generic φ3+φ4 model in d = 0 dimensions. We compare the first, and simplest, approximation in the above sequence with the one-loo...

Improved Dynami Spatial Approximation Trees

‏‎a 10-bit 50-ms/s parallel successive-approximation analog-to-digital converter‎‏

‏‎applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...

An Improved Approximation to the Distributions in GMM Estimation

The empirical saddlepoint distribution provides an approximation to the sampling distributions for the GMM parameter estimates and the statistics that test the overidentifying restrictions. The empirical saddlepoint distribution permits asymmetry, non-normal tails, and multiple modes. If identification assumptions are satisfied as the sample size grows the empirical saddlepoint distributions co...
