Dear Team,
I have a custom made LNA (shown in the attached image). I would like to ask about a suitable setup and procedure to measure noise and CMRR of this LNA.
As shown in the image the LNA is a single-stage diff amplifier with high output impedance. Therefore, I used a buffer (OPA355) at the output to measure the gain of the closed loop LNA, as shown in the attached setup image.
I am not able to upload images here but I have already sent the images via case CS0136479. Or please send me an email address to send the images?
Best regards
