Abstract
A current squaring cell is provided for producing an output current that correlates to the square of an input signal current. The current squaring cell comprises a first circuit portion, which receives a first tail current that is positively proportional to the input signal current, and a second circuit portion, which connects to the first circuit portion and receives a second tail current that is negatively proportional to the input signal current.
