Hi All,
I am designing a crystal oscillator in 28nm CMOS using 1.8V thick-oxide devices. It is a simple Pierce oscillator type design. The circuit is mostly done, but I need to meet the specs with certain supply noise injection, i.e. 200mVpp at 100Hz, 10kHz, and 1MHz. Are there any pointers or ideas about how to go about designing a supply filter for such a circuit? Any help would be greatly appreciated.
