DIGITAL TO ANALOGUE CONVERTING DEVICE
The invention relates to a digital to analogue converting device comprising a converting step establishing an upper (UL) and a lower voltage level (LL) in dependency of at least one digital input signal (DIS), said upper (UL) and lower voltage levels (LL) being time-modulated in dependency of at least said digital input signal (DIS) into a time-modulated output signal (TMOS), said time-modulated output signal having a period (T), said time-modulated output signal being fed through an output stage comprising at least one integrator (I), said integrator (I) being dimensioned in such a way that said time-modulated output signal is filtered and converted into an analogue representation of said digital input signal (DIS). According to the invention, a high-bit low-cost D/A-converter having small non-linearities has been obtained.
