Design of Low-Voltage Low-Power CMOS Delta-Sigma A/D Converters investigates the feasibility of designing Delta-Sigma Analog to Digital Converters for very low supply voltage (lower than 1.5V) and low power operation in standard CMOS processes. The chosen technique of implementation is the Switched Opamp Technique which provides Switched Capacitor operation at low supply voltage without the need to apply voltage multipliers or low VtMOST devices. A method of implementing the classic single loop and cascaded Delta-Sigma modulator topologies with half delay integrators is presented. Those topologies are studied in order to find the parameters that maximise the performance in terms of peak SNR....

The unmissable new book from the bestselling, prize-winning author of Landmarks, The Old Ways and The Lost Words Discover the hidden worlds beneath our feet... In Underland, Robert Macfarlane takes a dazzling journey into the concealed geographies of the ground beneath our feet - the hidden regions beneath the visible surfaces of the world. From the vast below-ground mycelial networks by which trees communicate, to the ice-blue depths of glacial moulins, and from North Yorkshire to the Lofoten Islands, he traces an uncharted, deep-time voyage. Underland a thrilling new chapter in Macfarlane's long-term exploration of the relations of landscape and the human heart. 'He is the great nature writer, and nature poet, of this generation' Wall Street Journal 'Packed with stories based in geography, history, myth, gossip, legend, religion, geology and the natural world. Macfarlane's writing moves and enthrals' The Times on The Old Ways 'Irradiated by a profound sense of wonder... Few books give such a sense of enchantment; it is a book to give to many, and to return to repeatedly' Independent on Landmarks
