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 … WebNov 13, 2024 · Mismatch between two resistors is defined to be [(Rbigger - Rsmaller) / Rsmaller] I fired up the computer and performed one hundred thousand trials. Each trial consists of: (a) Generate six random resistor values, uniformly distributed between 99 and 101 ohms; (b) for each possible resistor pair, calculate the mismatch; (c) report the best …
WebResistor Mismatch: Though resistors can be matched to a high degree of accuracy (typically 1%), resistor mismatch influences the PTAT voltage, which is a strong function of the ratio of the resistors R PTAT and R. From [8], a δ RR mismatch in these resistors leads to Δ = PTATδ RR = PTATδ RR t ref R V R V lnC V 2. (4)
