Third-Order ΣΑ Modulator with 61-dB SNR and 6-MHz
... A 5-bit DAC made by an array of capacitors would require using 32 unity elements whose value should be too small to ensure the required matching performance. For this reason, the DACs have been realized by using a resistive divider with 32 equal resistances of 200 . Moreover, in order to avoid int ...

Load-induced harmonics can cause motor and transformer overheating, mechanical resonances, and dangerously high currents in the neutral wires of threephase equipment. In addition, line distortions may violate regulator ...
