对二次谐波转移电子振荡器(TEO‘s)和异质结势垒变容管(HBV三倍频)的大信号时变特性进行了精确有效的模拟。这是通过使用一种新颖而高效的谐波平衡电路分析技术来实现的，该技术有助于集成基于物理的流体动力装置模拟器。集成的流体动力装置/谐波平衡电路模拟器允许从装置和电路的角度共同设计TEO和HBV型电路。与已发表的TEO和HBV二次谐波的实验数据进行了比较，对于TEO，在140 GHz和188 GHz的二次谐波下获得了良好的关联。对于工作在200 GHz附近的HBV三倍频也获得了很好的相关性。对于乙肝病毒，集总准静态等效电路模型和流体动力装置仿真器都已连接到谐波平衡电路仿真器。这种比较说明了用基于物理的数值器件模型而不是分析器件模型来表示有源器件的重要性。>；
Accurate and efficient simulations of the large-signal time-dependent characteristics of second-harmonic transferred electron oscillators (TEO's) and heterostructure barrier varactor (HBV) frequency triplers have been obtained. This is accomplished by using a novel and efficient harmonic-balance circuit analysis technique which facilitates the integration of physics-based hydrodynamic device simulators. The integrated hydrodynamic device/harmonic-balance circuit simulators allow TEO and HBV circuits to be co-designed from both a device and a circuit point of view. Comparisons have been made with published experimental data for both TEO's and HBV's. For TEO's, excellent correlation has been obtained at 140 GHz and 188 GHz in second-harmonic operation. Excellent correlation has also been obtained for HBV frequency triplers operating near 200 GHz. For HBV's, both a lumped quasi-static equivalent circuit model and the hydrodynamic device simulator have been linked to the harmonic-balance circuit simulator. This comparison illustrates the importance of representing active devices with physics-based numerical device models rather than analytical device models. >
