divider with the input voltage changes, the partial pressure of having different coefficients. Since the three diodes (VD1 ~ VD3) have different turn-on voltage, so as the input signal increases, the overall network impedance decreases, the results of the operational amplifier gain is increased. The resistance - the relationship between input and output diode network network, with an approximate square law characteristic, therefore, the whole forming a square-law converter circuit.
