CYCLE/VOLTAGE CONVERSION CIRCUIT

PURPOSE:To enable an outputting of exact voltage proportional to a cycle even if the load with low impedance is connected by connecting a buffer circuit on the output side of a smoothing circuit. CONSTITUTION:The output is inverted by an output inversion circuit in the manner of inputting a 1st signal, and the 1st output of output inversion circuit is made to the input by a gate control circuit and the control signal corresponding thereto is outputted. By a frequency dividing circuit 4, the output of gate control circuit is reset and also a 2nd signal is inputted to supply the frequency dividing output as a reset input of the gate control circuit. The 1st output of output inversion circuit and the output of gate control circuit are inputted to the 1st gate circuit 5, and the 2nd output of output inversion circuit and the output of gate control circuit are inputted to the 2nd gate circuit 6. Next, the outputs of gate circuits 5, 6 are supplied to the smoothing circuits 14, 15 through switch circuits 7-10 and outputted through the buffer circuits 16, 17. The exact voltage proportional to the cycle is thereby made possible to output.
