WebFeb 3, 2024 · \$\begingroup\$ The closed-loop will not really tell much to the designer. Actually, for any design with feedback, the open loop transfer characteristic is much more interesting (it tells you how stable it is with phase and gain margin, how much DC gain you have to reject noise and offsets, etc.) Also, in your case, you have a pure integrator, and … WebJul 22, 2015 · Yes - the 10 kHz channel spacing is probably the cause of the fractional-N spurs. Use the highest possible channel spacing. To add reference noise in ADIsimPLL, expand the Reference control, change the control to Point/Floor and insert the Point value from the reference source datasheet (it requires a dBc/Hz value and a frequency offset … WebSep 11, 2024 · 有些情况下,暂时没有合适的电阻和电容值,因此工程师必须确定是否能使用其他值。在 ADIsimPLL 的"工具"菜单中隐藏了一项小功能,称为"BUILT"。该功能可将电阻和电容值转换为最接近的标准工程值,允许设计人员返回仿真界面,验证相位裕量和环路带宽 … ftp completependingcommand
