IPC: H03L7/197
Filed: 1985-02-21
Abstract: PURPOSE:To obtain a frequency modulator operated stably with a low noise by applying an accurate current to an integration device added to a PLL circuit so as to reset the device. CONSTITUTION:When an output signal of the integration device 51 increases up to a preset high threshold value Vr1, a comparator 62 generates the 1st pulse.

When an input signal is negative, an output signal of the integration device 51 is increased negatively and when it reaches a preset low threshold value Vr2, a comparator 64 generates the 2nd pulse. Then the logic circuit 66 turns on a current source 54 and resets the integration device 51. Through the forming above, the frequency modulator operated stably with low noise is attained.
