Linear DC voltage multiplier circuit
This circuit has two ICL8048 logarithmic amplifiers, ananti-logarithmic amplifier ICL8049, anda 741 op-amp. The relationship between output voltage andtwo input voltages is: Vo=V1V2/10. V1 and V2are +0.1 ~ +10VDC voltage. When the output voltageis +10V, its accuracyis 1%.
