With the ongoing superheterodyne reciever project, I designed and simulated a recieve amplifier to amplify the signals coming from the antenna. I have chosen to use a bipolar junction transistor in the common emitter configuration as my amplifier.

Lately I have been chipping away at the idea of creating a superheterodyne reciever (and potentially tranciever). One of the key blocks within the design of a superheterodyne reciever is a mixer. I have a number of options when it comes to mixer topologies, and among them I wanted to give the gilbert cell a look.
