Problems solved by technology

[0002] Generally speaking, the frequency of the oscillating signal output by the oscillator (oscillator) in the prior art is usually easily affected by the voltage value deviation of the operating voltage, the change of the ambient temperature, and the variability of the semiconductor manufacturing process. The performance of a technical oscillator is very sensitive to changes in the external environment, so the frequency of the oscillator signal it outputs usually has instability problems

Embodiment Construction

[0013] Some terms are used in this specification and the following claims to refer to specific components, but those with ordinary knowledge in the art should understand that hardware manufacturers may use different terms to refer to the same component. The description and the subsequent claims do not use the difference in name as the way to distinguish the components, but the difference in the function of the components as the criterion for distinguishing. The "includes" mentioned in the entire description and the subsequent claims "Has" is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" here includes any direct and indirect electrical connection means. Therefore, if the text describes A first device coupled to a second device means that the first device can be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection mean...

Abstract

The present invention discloses an oscillation device which comprises a voltage regulation module, a current generation module, and an oscillation module; wherein, the voltage regulation module is used for generating a control voltage through an output endpoint, and comprises a first operational amplifier, a first switching element, and a first bleeder circuit; the oscillation module comprises an even number of switching elements which are connected in series, a current mirror module and an even number of capacitance modules. In the oscillation device, the frequency of oscillation signals of the oscillation module can not be influenced by the value excursion of the operating voltage, the change of environmental temperature, and the variability in the preparation process of the semiconductor.

Description

technical field [0001] The present invention relates to an oscillating device, especially an oscillating device that can make the frequency of an output oscillating signal not affected by the voltage value deviation of the operating voltage, the change of the ambient temperature, and the variability of the semiconductor manufacturing process. device. Background technique [0002] Generally speaking, the frequency of the oscillating signal output by the oscillator (oscillator) in the prior art is usually easily affected by the voltage value deviation of the operating voltage, the change of the ambient temperature, and the variability of the semiconductor manufacturing process. The performance of a state-of-the-art oscillator is very sensitive to changes in the external environment, so the frequency of the oscillator signal it outputs usually has instability problems. Contents of the invention [0003] In view of this, one of the objects of the present invention is to provi...
