The 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 low-voltage 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 2-/spl mu/m double-poly CMOS process available through MOSIS.
