ppm/'C is
for BGR
ppm/'C is defined by
maximum reference voltage - minimum reference voltage
------------------------------------------------------------------------------------ / Vref
temp(maximum reference voltage) - temp(minimum reference voltage)
Reference : D. Johns, K.Martin, <Analog integrated circuit design>, WILEY, p357
is this right?
e.g., ppm/'C of My BGR is
Vref=0.74V
0.74045-0.7396
------------------ = 11.65uV/'C
53.792-(-20)
11.65uV/'C
------------- = 15.75ppm/'C
0.74
Is this result 15.75ppm/'C right?
