目前，我们没有模拟和混合信号（AMS）电路的实际仿真解决方案，这与FPGA数字电路仿真的解决方案不同。提出了一种基于波形数字滤波器（WDF）的高Q值晶振电路仿真。基于文献[1]中提出的WDF，采用模拟电路仿真方法，覆盖了模拟电路从SPICE网表到FPGA硬件实现的整个流程。虽然WDF已被证明是有效的线性元件的电路，一个适当的方法来处理非线性元件，如MOS晶体管，是必要的。[2]提出了一种MOS晶体管的WDF模型，该模型可以解决传统非线性WDF模型中的连通性问题，同时保持模拟仿真的精度和效率。作为仿真示例，电阻电容（RC），共源极放大器（CS），和高Q晶体振荡器电路在WDF中实现，并比较其SPICE仿真验证的目的。
Currently, we have no practical emulation solution for analogue and mixed-signal (AMS) circuits, unlike resolutions found for FPGA digital circuit emulation. This paper presents a high Q crystal oscillator circuit emulation based on Wave Digital Filter (WDF). An analogue circuit emulation method was used based on WDFs proposed in [1] to cover the entire flow of transforming an analogue circuit from a SPICE netlist towards FPGA hardware implementation. Although the WDF has been shown to be effective for circuits with linear elements, a proper method for dealing with nonlinear components, such as MOS transistors, is required. [2] proposed a WDF model for MOS transistors that can solve the connectivity problem in traditional nonlinear WDF models while maintaining analogue emulation accuracy and efficiency. As emulation examples, Resistor-Capacitor (RC), Common Source amplifier (CS), and high Q crystal oscillator circuits were implemented in WDF and compared to their SPICE simulations for verification purposes.
