Hello All,
I have some general question about designing some Analog block and steps.
Lets consider we want to design simple Current Source biased by simple PMOS current source with given GAIN, GBW, CL
1. First should be from given GBW and load capacitance obtain the Gm
2. Then we from given Amplification(GAIN) and from Gm of step 1 we should decide what should be output resistance in order to achieve desired gain.
3. What next. Based on Gm and Rout we should obtain Current. Is that right?
4. We want some DC output level. How with all these parameters to design PMOS current source transistor and aplification NMOS such that to have proper DC, Output current, Gm and Rout??
Thank you in advance
