Title: Dynamic type frequency divider
Inventor: TAKAHASHI MASARU
IPC: H03K23/52
Filed: 1988-10-25
Abstract: PURPOSE:To easily cause a dividable frequency to be variable and to decrease a dividable lower limit frequency by using variable capacity or fixed capacity. CONSTITUTION:By attaching variable capacity diodes DI1 and DI2 to the output of transfer gates 3 and 5 in a dynamic type divider 1 and causing the capacity to be variable, the holding time of a charge is changed and the dividable frequency is made variable. Since the joining capacity of the variable capacity diodes DI1 and DI2 is made variable by a voltage, a voltage for capacity variability is added from an external part. When fixed capacity C3 and C4 are provided instead of the variable capacity diodes DI1 and DI2, a lower limit operating frequency can be decreased. Thus, by incorporating the variable capacity or fixed capacity, the dividable frequency can be easily made variable from the external part of an integrated circuit or the dividable lower limit frequency can be decreased.
