This book presents selected articles from INDIA SMART UTILTY WEEK (ISUW 2020), which is the sixth edition of the Conference cum Exhibition on Smart Grids and Smart Cities, organized by India Smart Grid Forum from March 03-07, 2020, in New Delhi, India. ISGF is a public private partnership initiative of the Ministry of Power, Govt. of India, with the mandate of accelerating smart grid deployments across the country. This book gives current scenario updates of Indian power sector business. It also highlights various disruptive technologies for power sector business.

A voltage-controlled oscillator (VCO) is one of the most important basic building blocks for analog and digital circuits. There are different implementations of VCOs. One of them is the ring oscillator based VCO. A ring oscillator based Temperature Sensors designed is sensitive for small variations of temperature. The Temperature is linearly dependent on the oscillation frequency of ring oscillator, as a way of converting temperature to a digital read out. The proposed temperature sensors occupies smaller silicon area with higher resolution than the conventional temperature sensors based on band gap reference. It was designed to achieve better than 1 DEGREESo C of temperature resolution, which is suitable for almost any application of an integrated CMOS temperature sensor. Special attention has been given to the integration of design of two different Ring Oscillators in order to achieve lower voltage operation when the design is implemented in an advanced CMOS p

Arithmetic circuits, like adders and multipliers, are one of the basic components in the design of communication circuits. In fact 8.72% of all instructions in a typical scientific program are multiplies. The multiplier is a fairly large block of a computing system. Multiplier is not only a high-delay block but also a significant source of power dissipation. That's why, if one also aims to minimize power consumption, it is of great interest to identify the techniques to be applied to reduce delay by using various delay optimizations. Array architecture is a popular technique to implement the multipliers due to its compact structure. In this book, six array multiplier circuits using different AND cells and XOR gates have been designed, simulated, analyzed and compared. This analysis should help shed some light on the low power and high throughput 2x2 array multiplier cells and should be especially useful for post graduate students and research scholars working in low power VLSI circuit design field."
