This book provides, for the first time, a broad and deep treatment of the fields of both ultra low power electronics and bioelectronics. It discusses fundamental principles and circuits for ultra low power electronic design and their applications in biomedical systems. It also discusses how ultra energy efficient cellular and neural systems in biology can inspire revolutionary low power architectures in mixed-signal and RF electronics. The book presents a unique, unifying view of ultra low power analog and digital electronics and emphasizes the use of the ultra energy efficient subthreshold regime of transistor operation in both. Chapters on batteries, energy harvesting, and the future of energy provide an understanding of fundamental relationships between energy use and energy generation at small scales and at large scales. A wealth of insights and examples from brain implants, cochlear implants, bio-molecular sensing, cardiac devices, and bio-inspired systems make the book useful and engaging for students and practicing engineers.

This is the journey of a person who hated the word ‘Sanghi’ but ended up happily adopting it as a label. Rahul Roushan shot to fame around 2009–10 as the ‘Pagal Patrakar’, the pseudonym he used while writing for Faking News. Back then he was seen just as a founder-editor of the news satire website with no special interest in politics or ideology. The first time Rahul Roushan was called a Sanghi, he felt deeply offended. After all, he held a Bachelor’s degree in Mathematics from Patna University, a post-graduate diploma in journalism from IIMC in New Delhi, an MBA from IIM Ahmedabad and was a self-made media entrepreneur. Sanghi literally means someone who is a member of the right-wing RSS (Rashtriya Swayamsevak Sangh) or its affiliates, but the ‘liberals’ use the term liberally to deride those who differ with their political and ideological stand, or those who wear Hinduism on their sleeves. This book analyses why Hindutva as an ideology is no longer anathema and what brought about this change. Why did a country that was ruled for decades by people espousing Nehruvian secularism suddenly began to align with the ‘communal politics’ of the Bharatiya Janata Party (BJP)? The book is the story of this transformation. This is not an autobiography, though it could read like one in parts. It is not even a collection of intellectual essays, though it could read like one in parts. It is the retelling of some historical events and how those events impacted the journey of Rahul Roushan and countless people like him. The book looks at factors like education, media, technology and obviously, electoral politics, which played a key role in this transformation.
