A Small-Signal Analysis Based Thermal Noise Modeling Method for RF SOI MOSFETs
نویسندگان
چکیده
We investigate thermal noise mechanisms and present analytical expressions of the noise power spectral density at high frequencies (HF) in Silicon-on-insulator (SOI) MOSFETs. The developed HF noise model of RF T-gate body contact (TB) SOI MOSFET for 0.13-μm SOI CMOS technology accounts for the mechanisms of 1) channel thermal noise; 2) induced gate noise; 3) substrate resistance noise and 4) gate resistance thermal noise. The extraction method of modeling parameter utilized by Y -parameter analysis on the proposed small-signal equivalent circuit is demonstrated in this paper. Excellent agreement between simulated and measured noise data is obtained at different temperatures.

In this article, a novel concept is introduced to improve the radio frequency (RF) linearity of partially-depleted (PD) silicon-on-insulator (SOI) MOSFET circuits. The transition due to the non-zero body resistance (RBody) in output conductance of PD SOI devices leads to linearity degradation. A relation for RBody is defined to eliminate the transition and a method to obtain transition-free c...
