Abstract

PURPOSE:To cause a frequency to be proportional inversely to the voltage to be converted, by utilizing the integral network having a prescribed integrating characteristic and by generating the saw tooth wave of a fixed inclination with the wave change value of the voltage to be converted. CONSTITUTION:Positive and negative DC voltages of absolute value E are applied to input terminals 1 and 2. When input terminal 2 is connected to integral network 4 by switch 3, the output is increased linearly toward the positive direction according to time elapse, and the inclination becomes +kE/CR. The voltage to be converted is applied to control voltage input terminal 7, and this voltage is compared with the output of integral network 4 by comparator 5; and if they coincide with each othter, FF9 is set to switch 3 to the input terminal 1 side. Then, by changing the voltage of control voltage input terminal 7, a saw tooth wave having the frequency proportional inversely to the control voltage is obtained as the output of integral network 4.
