Patent DE-3260449-D1 (DE)
Title: Digital-to-analog converter for bipolar signals
Inventor: VAN DE PLASSCHE RUDY JOHAN
IPC: H03M1/80
Filed: 1982-05-03
Granted: 1984-08-30
Abstract: In a digital-to-analog converter for bipolar signals all the bits change when the signals pass through the zero level. This results in a poor signal-to-noise ratio owing the small signal and the large noise contribution by the switching transients. The invention proposes to add a digital number to or subtract it from the digital input signal as an offset. As a result of this, the switching point is shifted towards a higher amplitude, which improves the signal-to-noise ratio and the distortion in the case of digital audio signals.

Abstract: A working or buffer store (61, 62) is connected between a main or bulk store (74) and a vector processing unit (50). The buffer store contains one or more virtual vector registers operable under user control in register-to-register (RR) vector operations. A user instruction specifies the length of a vector operand to be processed, the type of operation to be performed, and which vector registers will be used. Vector processing is controlled by a series of programs (106) defined at the code level of the processing unit where for a given function or operation, the same program is used for both register-to-register and storage-to-storage processing. The latter processing is controlled by passing predetermined parameters to the program whereas register-to-register processing is controlled by passing parameters generated in response to user program instructions.

Abstract: The composite insulating layer is dry-etched in a reactive ion etching equipment by plasma action in a gaseous mixture of a fluorine compound and a first percentage of an oxidiser. The etching produces a tapered hole with the required slope in the top phospho-silicate glass layer. The composite layer is dry-etched in the gas mixture with a second percentage of the oxidiser to transfer the required slope from the top insulating layer to the bottom insulating layer. The slope of the taper is modified. Then the dry etching in the gas mixture is repeated with a third percentage of oxidiser to adjust the slope of the tapered hole in the top layer to the required slope whilst leaving the slope in the bottom layer unaffected.
