A low voltage square root domain filter based on the MOSFET square law is proposed. Through the verification of HSPICE simulation, the extendibility and the reliability of the design procedure are proven. A design technique for current-mode square-root domain band-pass filter simulation in a 0.18 μm CMOS process. The basic building block consists of current-mode current mirrors, square-root cir...

In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...

We describe the implementation of the reciprocal square root — also called inverse square root — as a native function in the MPFR library. The difficulty is to implement Newton’s iteration for the reciprocal square root on top’s of GNU MP’s mpn layer, while guaranteeing a rigorous 1/2 ulp bound on the roundoff error. The reciprocal square root is an important function in 3D graphics, for the no...

BACKGROUND Providers use risk-adjustment systems to help manage healthcare costs. Typically, ordinary least squares (OLS) models on either untransformed or log-transformed cost are used. We examine the predictive ability of several statistical models, demonstrate how model choice depends on the goal for the predictive model, and examine whether building models on samples of the data affects mod...
