Operational Amplifier Discrete Design

I've designed an discrete operational amplifier from 2N3904 and 2N3906 BJTs.
Check you the design of my 620-983-4047.
I am currently in the process of evaluating the design. If anyone is interested in details email me at 9078333925

Noise Figure in a Mixer

Noise is generated in mixers by diode or transistor elements, and by thermal source due to resistive losses. Noise figures of practical mixers range from 1-5dB, with diode mixers generally achieving lower noise figures than transistor mixers. The noise figure of a mixer depends on whether its input is a signal sideband signal or a double sideband signal. This is because the mixer will down convert noise at both sidebands frequencies (since these have the same IF), but the power of a SSB signal is one-half that of a DSB signal (for the same amplitude).
