A circuit which accepts input dc voltage V I and produce an output voltage V O = √ V I V T by using double dual slope principle is described in this Letter. V T is a constant voltage which is fixed by two resistors and a power supply voltage. By using precision resistors and a stable constant power supply, an acceptable level of accuracy can be obtained.
