Voltage to Pulse Duration Converter Circuit
This is a design circuit for voltage to pulse duration converter. This circuit is control using op amp 741. This is the figure of the circuit;
This circuit is used to convert voltage into pulse duration by combining a timer IC and an OP Amp. This circuit can obtain accuracy up to better than 1%. The output signal is independent of the input voltage and still retain the original frequency.
