Find the output voltage of squarer circuit?

(a) Vo = √( Vref/|Vin|)

(b) Vo = √( Vref×|Vin|)

(c) Vo = √( Vref^2×|Vin|)

(d) Vo = √( Vref×|Vin|^2)

The question was asked in an internship interview.

Accurate answer is (b) Vo = √( Vref×|Vin|)

For the easiest explanation: The output of the square root circuit is proportional to the square root of the magnitude of the input voltage.
