MTL(MOS translineer loop)

[alikemal]

Hi. Is MOS translineer loop 2 quadrant multiplier or what? if it is why? Thank you...

Inter alia, yes. Find here a pamphlet by Eric Vittoz on this subject: View attachment Vittoz_Analog_VLSI_Signal_Processing__Why_Where_and_How.pdf

Thank you. it is a good resource about MTL but it does not contain any information about my question.

... it does not contain any information about my question.

I think for the 1^st part of your question:

Is MOS translineer loop 2 quadrant multiplier or what?

it does: s. p. 13, Fig. 13 of Vittoz' overview article:

... the multiplication/division of current signals is best achieved by using translinear circuits. A simple example is illustrated in Fig.13.

My

Inter alia

from above means there are more possible applications for translinear loop circuits than just (2 quadrant) multiplication. E.g. it can also be used to evaluate the mean square value of 2 currents.

I admit your 2^nd part of your question

if it is why?

isn't answered explicitely. I found one more article by E. Vittoz about translinear circuits with some more explanation: View attachment Vittoz__Translinear_circuits.pdf. If you need more, I'd suggest to search the corresponding literature.
