Thermal Modeling and Device Noise Properties of Three-Dimensional–SOI Technology
نویسندگان
چکیده
Thermal test structures and ring oscillators (ROs) are fabricated in 0.18-μm three-dimensional (3-D)–SOI technology. Measurements and electrothermal simulations show that thermal and parasitic effects due to 3-D packaging have a significant impact on circuit performance. A physical thermal model is parameterized to provide better prediction of circuit performance in 3-D technologies. Electrothermal simulations using the thermal model show good agreement with measurement data; the model is applicable for different circuits designed in the 3-D–SOI technology. By studying the phase noise of ROs, the device noise properties of 3-D–SOI technology are also characterized and compared with conventional bulk CMOS technology.

A Small-Signal Analysis Based Thermal Noise Modeling Method for RF SOI MOSFETs
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) ga...

متن کاملOutput-Conductance Transition-Free Method for Improving Radio-Frequency Linearity of SOI MOSFET Circuits
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...
