Summary

Translinear analog square root circuit. V(OUT) = SQRT( V(IN) ) / 10


Description

Concept: performs analog square root using the logarithmic voltage-current relationship of BJTs.

In response to "Extracting the Square Root of a Voltage" on Electronics Stack Exchange: http://electronics.stackexchange.com/questions/78294/extracting-the-square-root-of-a-voltage

Translinear square root core from Prof. Joel Dawson, MIT, notes http://www-mtl.mit.edu/~jldawson/documents/jldrec18.pdf (full course notes http://www-mtl.mit.edu/~jldawson/6301_notes.html)
