I am designing a low phase noise crystal oscillator. The noise of the supply(need 9V and 10mA current) is critical! So i need to suppress the noise from regulaor to about 7nV/sqrt(Hz) noise floor(about 100 or 1k to 1MHz). The 723 regulaor output noise is about 20uV(from 100 to 10kHz). It's much larger noise than i need(equal to 0.7uV from 100 to 10kHz) . Can some one suggest some circuit to do these? How about noise clipper circuit?
