Remarkable improvements have been recently reported on single-channel time-interleaved charge-based SAR ADCs to achieve sampling rates in the range of GS\/s with excellent power effeciency but the challenge of driving a large sampling capacitor with high accuracy in a short sampling window is often not addressed. In this work, a high-speed current-mode DAC is replacing the commonly used charge-mode SC-DAC which alleviates the problem of driving a large input sampling capacitor in a short time. The proposed current-mode SAR ADC also uses a Gm stage which converts the input voltage to a current which is then processed in a current-based binary search algorithm SAR loop. In comparison to the conventional SC-SAR ADC structures, the sampling capacitor size is smaller than the total capacitance of the comparable SC-SAR ADCs. Moreover, low-impedance DAC-reference voltages which are essential for SC-DAC are removed by using this approach.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786139928019\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786139928019","offer_id":39455297208413,"sku":"9786139928019","price":61.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e9f03d28-3e18-4287-8d8d-08c2537a0c3c.jpg?v=1770791837","url":"https:\/\/shop.autorenwelt.de\/products\/concept-and-design-of-a-high-speed-current-mode-based-sar-adc-von-abdelrahman-elkafrawy-maurits-ortmanns","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
