In this paper, an ultra low-voltage and low-power exponential V-1 converter is developed, using Taylor series expansion for realizing the exponential characteristics. The new CMOS exponential V-I converter is based on the composite NMOS transistors. The newly proposed appronmation function based on Taylor’s concept is used to extend the dB-linear output current range. In a 0.25 pm CMOS process,...

Although the random sum distribution has been well-studied in probability theory, inference for the mean of such distribution is very limited in the literature. In this paper, two approaches are proposed to obtain inference for the mean of the Poisson-Exponential distribution. Both proposed approaches require the log-likelihood function of the Poisson-Exponential distribution, but the exact for...

Abstract: The exponential distribution is a popular model in applications to real data. We propose a new extension of this distribution, called the Lomax-exponential distribution, which presents greater flexibility to the model. Also there is a simple relation between the Lomax-exponential distribution and the Lomax distribution. Results for moment, limit behavior, hazard function, Shannon entr...

This paper presents a linear multiplier that can be fully implemented in CMOS technology. The circuit implements the function of mathematical multiplication for the two input signals. Since this multiplier is not a conventional mixer, some unconventional methods were use, such as, to realize the function of multiplication, a translinear loop is implemented, which is based on the exponential rel...
