I need to check AC PSRR of an ADC, one thing First is i need to ride an AC sinusoid to a DC level. Usually it can be done with blocking cap series on Signal gen and an inductor series on a DC supply meeting at a point on power input. However, frequency range is from 10Khz to 500Mhz, it may degrade AC magnitude in terms of Accuarcy specifically on high frequencies(im using fixed inducor-1mH and fix capacitor-1oouF)? Is there an effective way to couple AC and DC across wide band frequencies? Is it possible to use bias tee??
