Barrel shifter is a elementary block of numerous computing systems due to its operation that it can shift and rotate multiple bits in one cycle. The barrel shifter can replace arithmetic and the logical shifters as it uses the rotation of the data. In 2018 Barrel shifters were designed using Adiabatic logic. Adiabatic logic is one of the common technique used to minimize energy loss and it can be used in analog as well as digital logic design.

The major challenge in orthogonal frequency division multiplexing (OFDM) is to reduce high peak to average power ratio (PAPR) that leads to non linear distortion for the application of high power amplifier. PAPR is defined as the ratio between the maximum instantaneous power and its average power. In this paper, we have presented new PAPR reduction technique to reduce peak to average power ratio using Linear predicting coding (LPC) in OFDM system.

Sense amplifier plays an important role in semiconductor memories which used to sense the stored data in memory cell. Two most important parameters like sensing delay and voltage are used in sense amplifier. Sense amplifier reduces the overall sensing delay and voltage. Voltage mode sense amplifier detects the voltage difference between bit-line and bit-line bar but when increases the memory size the bit-line and bit-line capacitance also increases. In this paper all circuit design analysis using Tanner 14.1 version simulation tool at 1.5v/45nm CMOS Technology.
