I am designing an active down mixer for BT applications.
The receiver is a direct conversion type. I am facing a big difficulty in getting gain and noise figure requirements.
The low frequency noise is due to the bias current of the mixer. I cant reduce the bias current as i lose the gain.
Can any one suggest me how can i improve noise figure without losing gain??
