possibilities. Security and power management are essential for billions of devices that perceive, compute, communicate, and interact. The physically unclonable function (PUF) is becoming increasingly essential in hardware-security applications because it gives device variations an object-specific physical identity that is hard to disclose and replicate by adversaries. Creating a tiny PUF that can withstand voltage, temperature, and noise is tough. This thesis proposes PUFs with two ultrasmall analog circuits that output absolute temperature. Two works demonstrate the proposed method: (1) an ultracompact and robust PUF based on voltage-compensated proportional-to-absolute-temperature voltage generators, which takes up 8.3 less area than the previous work and twice the robustness of the most compact PUF design; and (2) a method to transform a 6T-SRAM array into a robust analog PUF with minimal overhead. This work uses a similar circuit design to convert an on-chip SRAM into a PUF, lowering size in (1) without sacrificing robustness.
Just like how a puzzle needs to be put together in the right way to work, the VLSI circuit needs to be carefully designed and manufactured to function properly. Engineers use special computer programs to plan and create these circuits, making sure everything fits together perfectly.
When battery replacement is expensive, an Internet of Things sensor node needs energy harvesting. EH, PMUs lose efficiency during voltage transfer from harvester to battery and battery to load. A capacitor buffers energy flow in an EH PMU with hybrid energy storage. Key Words: VLSI Design, IoT Applications, Circuit Approaches, Low Power Design, Energy Efficiency, UltraLow Power.

1. INTRODUCTION A VLSI circuit is like a tiny electronic puzzle made up of many small components called transistors. It is designed to perform specific tasks by controlling the flow of electricity. Think of it as a mini-orchestra conductor that guides the movement of electrons to create useful functions.
In simple terms, a VLSI circuit is a small electronic puzzle made of tiny switches that control electricity. It is designed to do specific jobs and is used in many of the electronic devices we use every day.
These circuits are made of a special material called silicon, and they are so small that you need a microscope to see them. Each transistor acts like a switch, allowing or blocking the flow of electricity. By arranging these switches in clever ways, we can make the circuit do different things, like adding numbers, storing information, or even playing music.
1.1. Factor Affecting Performance of VLSI Circuit Several factors can affect the performance of a VLSI (Very Large Scale Integration) circuit. Here are some key factors to consider:
The VLSI circuit is all about making connections. It has pathways called wires that connect the transistors, allowing them to work together as a team. The design of these
