I'm trying to open schematics from a library made on "cadence 6" on "cadence 5141" and i get this error
"*WARNING* ddMapGetFileViewType: You are trying to run a CDB executable on an OA library file 'sch.oa'. The file is in library '******' in cell '******' in view 'schematic'. You must run an...
to get the mixer conversion gain I've tried the single tone test and pss and evaluated the gain ... now i want to evaluate it using PSS and PAC using some tutorials but I've got weird results ... so do you recommend a good tutorial for this simulation
I'm using Cadence with tsmc 130nm technology file ... and it's my first time ... now I'm facing a weird problem i have built a very simple circuit (an NMOS with its drain connected to the gate in series with an ideal current source between VDD and GND) I'm trying to apply the famous saturation...
look .. I'm in the beginning of my design (+ It's my first time) and I need a good reference book explaining different mixer design and design issues ... to select the appropriate design for my application.
i'am designing an RF system and i've obtained the overall system requirements from the standard (e.g the overall wanted gain) now i need to distribute that gain to the system blocks but i need to know "based on what !!" (or what is the efficient method used in distributing it)...
after obtaining the overall system specifications (Gain , NF ,IIP3 , ...) now i want to start distributing them (from overall specs. to block specs.)
what is the best method for doing that ?? ... or could you please suggest a good reference.
thanks in advance
