InP衬底上电容和电阻的建模

在射频集成电路中，Inp衬底的高电阻率导致了低衬底损耗以及器件和电路性能的提高。该文提出了Inp衬底上MIM电容和电阻的简单而精确的等效电路模型。测量结果与等效电路的仿真结果拟合得非常好，从而证明该文提出的模型足以准确地描述Inp衬底上MIM电容和电阻的电磁场特性。另外，Inp和GaAs同属于Ⅲ-Ⅳ族化合物。它们具有相似的性质，因此，该文提出的模型同样适用于GaAs衬底上的电容和电阻。

Modeling of InP-Based Capacitors and Resistors

In RFIC,the high resistivity of InP substrate results in low substrate loss and the improvement of devices and circuits' performance.Simple and accurate equivalent circuit models for InP-based MIM capacitor and resistor have been developed in this paper.Excellent agreement is achieved between measured and simulated data.It proves that the proposed models are accurate enough to describe the electromagnetic characteristics of InP-based MIM capacitors and resistors.InP and GaAs belong to III-V group semiconductor compound and they have similar properties,so the models proposed by this paper are fit for GaAs-based MIM capacitors and resistors.
