چکیده
The CORDIC (Coordinate Rotation Digital Computer) algorithm is a well-known versatile approach, which can be used to implement a large variety of arithmetic functions. Consequently, it is widely applied in Digital Signal Processing (DSP) on today’s SoCs. Typical tasks comprise Numerically Controlled Oscillator (NCO), phase rotation, equalization, modulation and demodulation, DCT [1], to name a few. In future, further applications for CORDIC building blocks can be expected, for example Singular Value Decomposition (SVD) in sophisticated algorithms for spatial filtering and direction of arrival estimation in communication and navigation systems [2,3].

A Simple General-purpose I-V Model for All Operating Modes of Deep Submicron MOSFETs
A simple general-purpose I-V model for all operating modes of deep-submicron MOSFETs is presented. Considering the most dominant short channel effects with simple equations including few extra parameters, a reasonable trade-off between simplicity and accuracy is established. To further improve the accuracy, model parameters are optimized over various channel widths and full range of operating v...

-The optimization of the input MOSFET for charge amplifiers in deep submicron technologies is discussed. After a review of the traditional approach, the impact of properly modeling the equivalent series noise and gate capacitance of the MOSFET is presented. It is shown that the minimum channel length and the maximum available power are not always the best choice in terms of resolution. Also, in...
