A sinusoidal frequency to voltage converters using op-amp based triple integrators, dual comparator and dual peak detectors, is explained in this paper. The output DC voltage is linearly proportional to the sinusoidal input frequency. The proportional constant is the product values of a resistor, a capacitor and a reference DC voltage. By employing precision values for these three quantities, an acceptable level of accuracy can be achieved. Verification of feasibility of the circuit is established by way of test results. |
