Implementation of Carry Select Adder with Reduced Area Scheme
Abstract: Addition is the heart of arithmetic unit and the arithmetic unit is often the work horse of a computational circuit. So, adders play a key role in designing an arithmetic unit and also many digital integrated circuits. Carry select adder (CSLA) is one of the fastest adders used in many data processors and in digital circuits to perform arithmetic operations. But CSLA is area-consuming because it consists of dual ripple …

Self-Compensation of Commutation Phase Error for Brushless DC Motor
Abstract: BLDC motors are synchronous motors powered by DC electricity via an inverter which produces an AC electric current to drive each phase of the motor via a closed loop controller. Electronic commutation is the on-and-off of the semiconductor switches at appropriate time to turn stator windings. Commutation phase ripple is generated due to the different exchange rate between outgoing phase current and incoming phase current of inverter during commutation period. …
