| description |
In this study, the noise characteristics of a carbon resistor is analyzed and
compared at room and liquid nitrogen temperatures. The procedure for the
noise measurement of the resistor is explained, along with the components
of the experimental setup. Background material such Fast Fourier transform
which is essential for digital signal processing is introduced. In addition,
using a printed circuit board design software known as Altium, a laser current
driver which has a sub-circuit that allows for modulation input was designed
and then subsequently fabricated into a printed circuit board. The laser
current driver, which is updated from the Hall Libbrecht current driver, aims
to achieve a high degree of stability and low level of noise. |
