The student and professor duo from Indian Institute of Science ( IISc) has come up with a novel method facilitating miniaturization of Very Large Scale Integration (VLSI) devices, which has an effective usage in baby monitors and heart rate monitors.
This innovative all- digital circuit manages power better and considerably reduces the power consumed by the device and is efficient, reliable and produces a hundred fold improvement for certain operating conditions.
Sagar Gubbi, a PhD student and Bharadwaj Amrutur, an associate professor from the Department of Electrical and Communication Engineering have proposed an entirely digital circuit, a tiny square side of 30 microns to achieve this.
This new all-digital method does not depend on analog voltage measurements. The optimizing circuit can be integrated into a circuit forming a part of the miniature that controls supply voltage to parts of a bigger system like a mobile phone, claims Sagar.
Its advantage over analog circuits can be seen from simulations performed and reported which show that in case of digital circuits, minimum energy point to an error is about 5% compared to analog circuits that have an error of 500%.
Sagar said, "Just as software eats the world, digital circuits are eating analog circuits."
