Abstract

Objectives: To solve timing and power consumption issues in digital circuit design by creating a Low-Power Shift Register Based on Pulsed Latch (LPSR-PL). Targeting IoT sensors and portable devices for low-power operation, increase energy efficiency in shift registers by using numerous non-overlapping delayed pulsed clock signals, decoder-enabled design, and gated clock circuits. Methods : The work uses a unique strategy that decreases power consumption and timing difficulties by employing numerous non-overlapping delayed pulsed clock signals in the LPSR-PL. To improve data synchronisation, it combines latches into temporary store latches. The study uses a decoder-enabled design to compress control logic and simplify clock-pulse circuitry, resulting in power reductions. In addition, a gated clock circuit is designed to save energy by preventing pointless clock pulses during times of inactivity or static operation. Findings : The LPSR-PL is a good choice for contemporary digital circuit design as it efficiently addresses timing problems and reduces shift register power consumption. The employment of several non-overlapping delayed pulsed clock signals improves operating efficiency and data synchronisation. The employment of gated clock circuits, decoder-enabled architecture, and non-overlapping clock signals has led to significant advancements in low-power shift register designs. For applications where energy conservation is crucial, such as Internet of Things sensors and portable devices, this technology provides a more energy-efficient option. The suggested model performs very well with a much reduced power usage of 0.502 W. Novelty: Power consumption and timing accuracy have been problems with conventional shift registers for a very long time. Conventional methods' dependence on a single pulsed clock signal often produced inefficiencies and subpar results. The LPSR-PL, however, has altered the rules of the competition today by offering multiple non-overlapping delayed pulsed clock signals that signify a new era in digital circuits.
