Multiple-input translinear element networks

We describe a class of nonlinear circuits that accurately embody product-of-power-law relationships in the current signal domain. We call these circuits multiple-input translinear element (MITE) networks. A MITE is a circuit element that produces an output current that is exponential in a weighted sum of its input voltages. We describe intuitively the basic operation of MITE networks and we show experimental data from a squaring-reciprocal circuit breadboarded from bipolar-floating-gate MOS (biFGMOS) MITEs that we fabricated in a 2-/spl mu/m double-poly CMOS process available through MOSIS.
