WebJun 25, 2024 · This suggests that the resistors implemented in the DAC has a low local mismatch, as will also be confirmed in a separate measurement. Another difference shown by measurement results compared to Fig. 10 (a) is the attenuation of the out-of-band noise shaping curve which reaches a peak at \(-\,60\) dB at slightly less than half the sampling … WebIn electronics, impedance matching is the practice of designing or adjusting the input impedance or output impedance of an electrical device for a desired value. Often, the desired value is selected to maximize power transfer or minimize signal reflection.For example, impedance matching typically is used to improve power transfer from a radio transmitter …
