We measured the static characteristics and noise spectra of FD-SOI-CMOS at liquid helium temperature where many bulk-CMOS transistors suffer from anomalous behaviors on the current-voltage curves such as kink phenomena. The test results showed that the static characteristics depend on the layouts of the FD-SOI-CMOS transistor. While a body floating FD-SOI-CMOS transistor showed strong anomalous effects on the I-V curves, body-tied and ST ones showed much better static characteristics than the body floating one. Using the characteristics derived from the FET measurements, we show that a low power and high gain preamplifier suitable for far-infrared detectors can be designed.
