Variable frequency oscillator and digital control oscillator |
| abstract |
(57) [Abstract] [Purpose] To provide a variable frequency oscillator capable of digital control. [Configuration] An odd number of 65 inverting circuits NAND and INV are connected in a ring shape, and the number of connected stages can be changed in units of two in the range of 33 to 65 by switching circuits SW1 and SW2. In addition, switching circuits SW1 and SW2 Is a 5-bit digital data CD input from the outside L is a switching signal DC in which only a specific signal goes low ON / OF by the decoder 20 converting from 0 to DC16 Enable F control. As a result, the inverting circuit NAND Since the pulse signal circulates in the ring formed by INV and INV, an oscillation signal having a desired frequency can be obtained by controlling the number of connecting stages and the number of revolutions of the inverting circuit at the time of circulation. |
