Hi All,

I've got the following specs for the design of source follower. I've been tryin it for last several days but unable to meet the specs. Please try and help with this.

Technology Details:

Lmin = 350nm

Output Impedance=100Ω

Load capacitance = 500f Farads

Voltage Swing >=2.5V

Unity gain Bandwidth >= 800MHz

Small signal input is fed from a 1 farad capacitor

PS: I'm still not clear what does unity gain b/w for common drain mean as the gain is always less than unity. Please help me guys.
