在Silvaco TCAD (Technology Computer-Aided Design) 软件中,为了得到电流控制器件(如MOSFET或IGBT等)的输出特性仿真曲线,通常需要编写脚本来设置电路模型、施加电压源、运行仿真,并分析结果。这里是一个简化的例子,假设你在Python语言中使用的是Siemens的PDK(Process Design Kit):
```python
from silvaco_pdk import *
# 设定设备参数
device = Device(name="MyDevice", tech_library=TechLib("your_tech_library"))
# 创建沟道
channel = device.create_channel(layer="nwell", doping="P")
# 设置栅极
gate = channel.create_gate(name="gate", workfunction="Vth", width="1um", length="1um", doping="N+")
# 添加偏置电源
bias = VoltageSource(name="bias", start_voltage=-5V, end_voltage=5V, step_size=0.1V)
# 运行DC sweep
sim = DC_Simulation(device)
sim.add_voltage_source(gate, bias)
sim.run()
# 获取并绘制I-V曲线
output_curve = sim.get_output_curve(' drain_current', 'voltage')
plot(output_curve, x_label="Voltage (V)", y_label="Current (A)")
