Abstract

The invention provides an oscillator, including a resistor, at least one first reverser, at least one second reverser and a capacitor bank. The at least one first reverser is connected with the resistor in parallel, and has an input end and an output end. The at least one second reverser has an input end and an output end, the input end of the at least one second reverser is connected to the output end of the at least one first reverser. The capacitor bank is connected with the input end of the at least one reverser and the output end of the at least one second reverser, and includes a first capacitor and a second capacitor, the first capacitor has a negative voltage coefficient, and the second capacitor has a positive voltage coefficient. By utilization of mutual compensation of the first capacitor and the second capacitor, the oscillator can be free of influence of voltage variation, so as to maintain stable output frequency.

Description

technical field [0001] The present invention relates to an oscillator. Background technique [0002] Oscillators are electronic circuits used to generate periodic signals, which can be sine waves, square waves, or triangle waves. The RC oscillator is a type of oscillator, which utilizes the charging, discharging and coupling of a resistor (R) and a capacitor (C) to output a periodic signal. Generally speaking, RC oscillators are more sensitive to changes in the manufacturing process of components, temperature or voltage, etc., and are greatly affected by the above changes. Contents of the invention [0003] The technical problem solved by the present invention is to provide an oscillator to solve or improve the above problems. [0004] The technical solution for solving the problem of the present invention is to provide an oscillator, including: a resistor, at least one first inverter, at least one second inverter and a capacitor bank. The at least one first inverter is...
