This book describes the concept and design of the capacitively-coupled chopper technique, which can be used in precision analog amplifiers. Readers will learn to design power-efficient amplifiers employing this technique, which can be powered by regular low supply voltage such as 2V and possibly having a +/-100V input common-mode voltage input. The authors provide both basic design concepts and detailed design examples, which cover the area of both operational and instrumentation amplifiers for multiple applications, particularly in power management and biomedical circuit designs.
Translated, with an Introduction and Notes by John R. Williams. Goethe's 'Faust' is a classic of European literature. Based on the fable of the man who traded his soul for superhuman powers and knowledge, it became the life's work of Germany's greatest poet. Beginning with an intriguing wager between God and Satan, it charts the life of a deeply flawed individual, his struggle against the nihilism of his diabolical companion Mephistopheles. Part One presents Faust's pact with the Devil and the harrowing tragedy of his love affair with the young Gretchen. Part Two shows Faust's experience in the world of public affairs, including his encounter with Helen of Troy, the emblem of classical beauty and culture. The whole is a symbolic and panoramic commentary on the human condition and on modern European history and civilisation. This new translation of both parts of 'Faust' preserves the poetic character of the original, its tragic pathos and hilarious comedy. In addition, John Williams has translated the Urfaust, a fascinating glimpse into the young Goethe's imagination, and a selection from the draft scenarios for the Walpurgis Night witches' sabbath - material so ribald and blasphemous that Goethe did not dare publish it. AUTHOR: Johann Wolfgang von Goethe (1749 - 1832) is widely acknowledged as the greatest writer of the German tradition. He began writing his masterpiece, the play 'Faust', at the age of twenty-three, and finished the second part just before his death. Building on an old legend of the scholar who makes a pact with the devil, Mephistopheles, his work has had an enduring reputation and influence.
