Abstract :
The demonstration, using HgCdTe MISFETs, of a sampling circuit with output buffer amplifier is reported. Using the circuit, correlated double sampling is demonstrated at speeds typical of those required for focal plane arrays. Using a swept sine input, the circuit´s transfer function is verified. The circuit was fabricated on epitaxially grown HgCdTe, with a cutoff wavelength of 3.56 mu m at 77 K.
