Patent number: 10879880Abstract: An oscillator including two sequentially connected pulse generation circuits is disclosed. Each pulse generation circuit includes a charge/discharge circuit and a switch circuit and outputs a first or second signal depending on an input signal. The switch circuit controls the charge/discharge circuit so that the latter is charged when the input signal is at a first level and discharged when the input signal is at a second level higher than the first level. When the input signal is at the first level, the first signal is at the first level and the second signal is at the second level. When the input signal is at the second level, the first signal is at the second level and the second signal is at the first level. Upon completion of discharge of the charge/discharge circuit, the first signal changes to the first level and the second signal changes to the second level.Type: GrantFiled: December 5, 2018Date of Patent: December 29, 2020Assignee: WUHAN XINXIN SEMICONDUCTOR MANUFACTURING CO., LTD.Inventor: Yuan Tang
