The M\/2\u003csup\u003e+\u003c\/sup\u003eM sub-binary digital-to-analog converter is thoroughly studied, and the use of this very low-area circuit in conjunction with a successive approximations algorithm for digital compensation is described. A complete methodology based on this compensation circuit and algorithm is then proposed. The detection and correction of analog circuit imperfections is studied, and a simulation tool allowing the transparent simulation of analog circuits with automatic compensation blocks is introduced. \u003c\/p\u003e\n\u003cp\u003eThe first application shows how the sub-binary M\/2\u003csup\u003e+\u003c\/sup\u003eM structure can be employed as a conventional digital-to-analog converter if two calibration and radix conversion algorithms are implemented.\u003c\/p\u003e\n\u003cp\u003eThe second application, a SOI 1T DRAM, is then presented. A digital algorithm chooses a suitable reference value that compensates several circuit imperfections together, from the sense amplifier offset to the dispersion of the memory read currents.\u003c\/p\u003e\n\u003cp\u003eThe third application is the calibration of the sensitivity of a current measurement microsystem based on a Hall magnetic field sensor. Using a variant of the chopper modulation, the spinning current technique, combined with a second modulation of a reference signal, the sensitivity of the complete system is continuously measured without interrupting normal operation. A thermal drift lower than 50 ppm\/°C is achieved, which is 6 to 10 times less than in state-of-the-art implementations. Furthermore, the calibration technique also compensates drifts due to mechanical stresses and ageing. \u003c\/p\u003e\n            \u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9789048170876\"\u003e\u003ch3\u003ewith Case Studies\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9789048170876","offer_id":39416538267741,"sku":"9789048170876","price":160.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f11e7d7e-a488-4232-8b59-26a3ecffe898.jpg?v=1766646708","url":"https:\/\/shop.autorenwelt.de\/products\/methodology-for-the-digital-calibration-of-analog-circuits-and-systems-with-case-studies-von-marc-pastre-maher-kayal-1","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
