It has been shown that, one over f noise' (1/f noise) limits the sensitivity in Mercury Cadmium Telluride (HgCdTe) infrared devices. It is therefore imperative to be able to measure and account for its contribution to the total device noise. In this thesis, the 1/f noise of a HgCdTe device is measured and studied using two measurement techniques. The first technique is the commonly used conventional method of measuring 1/f noise that analyzes 1/f noise in the frequency domain and extracts the 1/f noise contribution from the power spectral densities. The second approach is a novel technique that extracts the …
