Regulator of a digital-to-analog converter and related converter
Abstract
A description has been given of a regulator for a digital-to-analog converter having in input a digital signal (BUS) and being suitable for providing an analog signal (Vout) in output. The regulator comprises at least one pair of buffers (Buf1, Buf2..Bufn) having in input said digital signal (BUS) and the outputs connected to a pair of circuit branches (r1, r2..rn) connected to the output of the regulator; each of said at least two circuit branches comprises at least one resistance. To at least one (Buf2, Buf3...Bufn)) of said at least one pair of buffers a variable resistance (Rv2...Rvn) is associated and the regulator comprises means (10) having in input the analog signal and being suitable for measuring its trend and acting on the variable resistance (Rv2...Rvn) in response to its possible anomalous trend compared to a desired trend.
