Linear Direct Current Voltage Multiplier(ICL8048,ICL8049) Circuit
The picture shows the linear direct current voltage multiplier circuit. The circuit uses two ICL8048 logarithmic amplifiers, one antilog amplifier ICL8049 and one 741 operational amplifier. The relation between the output voltage and the two input voltages is: Vo=V1V2/10. In the circuit, V1 and V2 are direct current voltage of +0.1-10V. When the input voltage is +10V, the precision is 1%.
