So i am building a front end of some type of circuit and it appears that the first stage of the circuit I make is being affected by the output impendance of the previous stage. Before my circuit there is a VGA. So what is the typical output impendance of VGAs in 0,18u technologies? I am more concerned about the real part. I dont want an exact number just an area of resistances to be correct. I suppose they have a low real part. I have already found an area where my circuit works optimally but i want to be relevant. The VGA works at 5Mhz.
Thank you.
