本文描述,论证并用实例说明了一种选择SOI MOSFET适当模型的实验方法。选择的准则是由薄膜和(半)体器件模型所预测的稳态电流——电压特性导出的。通过揭示(看似正确的)实际经验模型所产生的明显的模拟误差,突出了选择适当模型的必要性。 相似文献

Ultrathin silicon-on-insulator (SOI) layers of separation by implantation of oxygen (SIMOX) wafers have been transferred onto
thermally oxidized silicon wafers by wafer bonding technology. Due to the technical availability and the complementary nature
of SIMOX and wafer bonding approaches, SIMOX wafer bonding (SWB) solves some of the respective major difficulties faced by
both SIMOX and wafer bonding for device quality ultrathin SOI mass production: the preparation of adequate buried oxide (including
its interfaces) in SIMOX and the uniformly thinning one of the bonded wafers to less than 0.1 μm in wafer bonding. The effect
of positive charges in the oxide on bondability of ultrathin SOI films and possible applications of SWB will also be outlined. 相似文献

Thanks to their structure, the SOI technologies present several intrinsic advantages for analog and RF applications. Indeed, as it is well established now, these technologies allow the reduction of the power consumption at a given operating frequency. Moreover, the high-insulating properties of SOI substrates, in particular when high resistivity substrate is used, make that these technologies are perfect candidates for mixed-signal applications. In the present paper, we will discuss the performances of the SOI technologies in radio-frequency range. First of all, the high-frequency behavior of SOI substrates, thanks to the characterization of transmission lines, will be shown. The impact of the SOI substrate resistivity on the performances of passive components will also be analyzed. Then, an overview of RF performances of SOI MOSFETs for two different architectures, fully- and partially-depleted, will be achieved and compared to the bulk ones. Finally, the influence of some specific parasitic effects, such as the kink effect, the self-heating effect and the kink-related excess noise, on the RF performances of SOI devices will be studied, thanks to a specific high-frequency characterization. 相似文献

There is increasing interest in the use of CMOS circuits for high frequency highly integrated wireless telecommunications systems. This paper presents the results of on-going work into the development of a cell library that includes many of the circuit elements required for the high frequency sub-systems of communications integrated circuits. The cell library studied included an RF control element, single ended Class A amplifier, RF isolator, and Gilbert cell mixer circuit topologies. Circuit design criteria and measurement results are presented. All cells were fabricated using standard 2.0, 1.2, and 0.8 m CMOS integrated circuit fabrication processes with no post-processing performed. The results indicate that 2.0 m CMOS can be used successfully up to approximately 250 MHz with 0.8 m cells useful up to approximately 1000 MHz. 相似文献
