Abstract
Embodiments of the present application provide an oscillator and a clock generation circuit. The oscillator includes: a first ring topology, including a plurality of first inverters connected end to end, and configured to transmit an oscillation signal at a first transmission speed; and a second ring topology, including a plurality of second inverters connected end to end, and configured to transmit the oscillation signal at a second transmission speed, wherein the present application, the first ring topology is electrically connected to the second ring topology, and the second transmission speed is less than the first transmission speed.
Claims19
An oscillator, comprising:
- a first ring topology, comprising a plurality of first inverters connected end to end, and configured to transmit an oscillation signal at a first transmission speed;
- and
- a second ring topology, comprising a plurality of second inverters connected end to end, and configured to transmit the oscillation signal at a second transmission speed, wherein
- the first ring topology is electrically connected to the second ring topology, the second transmission speed is less than the first transmission speed,
- the first transmission speed is adjustable,
- the first transmission speed is adjustable by adjusting at least one of a pull-up capability or a pull-down capability of the plurality of first inverters,
- the pull-down capability of the plurality of first inverters is increased when the pull-up capability of the plurality of first inverters is increased, and
- the pull-down capability of the plurality of first inverters is decreased when the pull-up capability of the plurality of first inverters is decreased.
