A method for producing an oscillating signal comprises: generating an oscillating signal by discharging after charging to a high trigger level and charging after discharging to a low trigger level; and turbo-charging at the initial of a change-over from charging to discharging while resuming a normal charging/discharging thereafter, and vice versa. The present invention makes use of the turbo-charging/discharging for a linear compensation, such that the produced oscillating signal has the features of concurrently eliminating phase noises and jitters as well as maintaining the modulation linearity.
