Hello Forum,
I am working on the design of a Gilbert Cell Mixer.
My Goals are:
1. Vdd should be 1V
2. Total current Idd approximately equal to 500µA-1mA
3. Voltage Conversion gain >= 6dB
I have achieved this with the circuit attached below.
With inductive degeneration at the source of Gain stage, the optimum value obtained after parametric analysis is 15.5nH.
My question for this thread is,
1. Can the length of the transistors be 232nm for a 45nm technology?
2. What effects will the 15.5nH inductor value have on the layout and chip size?
I might be ignorant in a few concepts. Please feel free to correct me.
