Introduction: One of the possible techniques to cope with the restrictions imposed by llow supply voltages is instantaneous companding [l], which is an inherent characteristic of translinear (TL) filters [2], also called exponential state-space filters [3]. TL filters exploit the exponential large-signal behaviour of the bipolar, or weak inversion MOS, transistor both for an expanding capacitan...

متن کاملThe Multiple-input Translinear Element: a Versatile Circuit Element
We define the multiple-input translinear element (MITE), a versatile circuit primitive from which we can construct lowvoltage translinear circuits and log-domain filters. A K-input MITE produces an output current that is exponential in a weighted sum of its K input voltages. We briefly discuss six MITE implementations and show experimental data from two of these six that we have fabricated in a...
