Multiplier in Cadence Design virtuoso

[gk1994]

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 no user of Cadence, but from what I found on other sites "m" is a multiplier that instantiates multiple (m) instances of a device.
In this case I assume you want to use m = 2 MOSFETs.
If they are used in parallel, then that is equivalent to W_new = m × W_old and L_new = L_old.
If they are used in series, then that is equivalent to W_new = W_old and L_new = m ×L_old.
