Background: This article presents a 12-element Dipole Linear Array Antenna (DLAA) optimization using Gravitational Search Algorithm (GSA) to find optimal design parameters such as lengths corresponding to each dipole and spacing corresponding to separation between two neighbor dipoles. Methods: GSA optimizes the design parameters to offer the desired performance parameters such as high Directivity (DR), high Front to Read More

Background: In this paper, a novel instrumentation amplifier (IA) based on voltage differencing buffered amplifier (VDBA) is presented. The proposed IA consists of a single VDBA and a resistor and offers high common-mode rejection ratio (CMRR). The effects of non-idealities of the VDBA are analyzed and the corresponding mathematical formulation is derived. Methods: Theoretical analysis of the proposed circuit is verifie Read More
