Limited Common-Mode Rejection Ratio (CMRR) in balanced interfaces often limits dynamic range in real-world audio systems. Conventional differential amplifier input circuits suffer serious CMRR degradation when driven by real system signal sources instead of laboratory generators. An ideal audio transformer, because of its extremely high common-mode impedances, is virtually immune to this degrad...

This paper presents an implementation of an Advanced Encryption Standard (AES) encryption unit using dynamic reconfiguration based on the Xilinx Spartan-3 FPGA platform. The proposed design reuses resource of FPGA by adapting dynamic reconfiguration to reduce the number of resource used in the circuit. By changing circuits at runtime, the size of the whole circuit is limited to the largest reco...

Different cascode circuits are investigated with regard to their suitability for low-voltage and low-current circuits. A generalized circuit representation is introduced and different cascode circuits are discussed with respect to their small-signal parameters as well as their associated dynamic output ranges. The output voltage ranges for saturation operation of the different cascode circuits ...

In this paper, a novel approach for two-loop control of the DC-DC Ćuk converter in discontinuousconduction mode is presented using a sliding mode controller. The proposed controller can regulatethe output of the converter in a wide range of input voltage and load resistance. Controllerparameters are selected using PSO algorithms. In order to verify the accuracy and efficiency of thedeveloped sl...
