Patent number: 5204679Abstract: An analog-digital converter includes a differential amplifier having collector resistances each being in the form of a resistance line. Node points between resistance segments of the resistance lines are in the form of output terminals. Comparators with a balanced input are provided in the same amount as the resistance segments. In each case one input of a comparator is connected to an output terminal of a first resistance line and another input of the comparator is connected to an output terminal of a second resistance line. Therefore, the same resistance value in each case acts between two output terminals, which are connected to one comparator, in the collector circuit of the differential amplifier.Type: GrantFiled: August 14, 1992Date of Patent: April 20, 1993Assignee: Siemens AktiengesellschaftInventors: Hermann Jessner, Bernhard Zojer, Berthold Astegher

Patent number: 5072220Abstract: An analog/digital converter assembly includes a first analog/digital converter having N-bit resolution, operating by the parallel method and having comparators. A sample and hold element is connected upstream of the first analog/digital converter. A second analog/digital converter has M-bit resolution, operates by the parallel method and has comparators. A digital/analog converter is connected upstream of the second analog/digital converter. A subtractor is connected to the digital/analog converter and to the sample and hold element. An amplifier is connected downstream of the subtractor. Output signals of the comparators of the first analog/digital converter are provided directly with a 1.sup.x out of 2.sup.N code for triggering the digital/analog converter. The same reference voltage is applied to both the first analog/digital converter and the digital/analog converter.Type: GrantFiled: February 14, 1991Date of Patent: December 10, 1991Assignee: Siemens AktiengesellschaftInventors: Reinhard Petschacher, Berthold Astegher
