Abstract (en)
[origin: WO0057558A2] The invention relates to a 1-bit digital-analogue converter circuit comprising outputs, switching units and pulse shaping units. Said outputs, switching units and pulse shaping units are decoupled from one another by decoupling units. The invention also relates to a 1-bit digital-analogue converter which has one or two outputs, two inputs, a switching unit and pulse shaping units. Each input is configured in a pair and each switching unit has a second switching unit allocated thereto, in such a way that each bit variation of the input bit forces a switching process to occur. In the case of a current switching i, the current i is adjusted to almost or exactly zero, whilst in the case of a switching to an electric potential, the corresponding potential difference is adjusted to almost or exactly zero.
