I've read that a JFETs near their cutoff points are "square law devices". Does this literally mean I can use their amplification to solve the equation output=input^2 in analog? I'm asking because I've looked at how analog computers square numbers and its always sequence of op-amp logarithmic and antilogarithmic amplifiers. Why would people do that if they can get the same behavior from just a JFET and resistor?
