Hi All,

Just a basic question in Cadence Design about multipliers(m)

Say if m = 1, width= 2,4u and Length = 180n, so if I make the m = 2, only the width gets doubled and the length remains constant ( width= 4,8u and Length = 180n). Is this right ?

I'm assuming you're referring to transistor sizing? If so, while I'm not 100% sure, I believe that is correct based on my past experience, as the "multiplier" is there to let you scale up or down the current-handling capabilities (for instance, an "m" of 2 would me that the channel, being twice as large, can theoretically handle twice the current). The process size is defined by the length in this case (a 180nm process).
