hi
i have designed a passive mixer. for this individually i have tested TCA, TIA and switcing quard. all three are working fine individually. as i m trying to integrate its not working. so i reied one by one. now i got to know the problem. TIA is working upto only 2 MHZ. as i m putting any other ac source that is not connected to TIA at all then also TIA transient response is degrading. plz tell me why this is happening.
