【 摘 要 】

A circuit which accepts input dc voltage VI and produce an output voltage VO = √VIVT by using double dual slope principle is described in this Letter. VT 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.
