Title:
RAMP GENERATOR, ANALOG-TO-DIGITAL CONVERTER AND METHOD FOR CONTROLLING GENERATION OF RAMP SIGNAL
Document Type and Number:
WIPO Patent Application WO/2020/211303
Kind Code:
A1
Abstract:
The present application relates to a ramp generator, an analog-to-digital converter and a method for controlling the generation of a ramp signal, and relates to the field of signal control. The ramp generator comprises: a current source, a signal generator and a controller, wherein an output end of the current source is connected to an input end of the signal generator; an output end of the signal generator is connected to an input end of the controller; an output end of the controller is connected to an input end of the current source; the signal generator is configured to generate a ramp signal according to a current output by the current source; the controller is configured to adjust a feedback voltage according to the ramp signal, and the adjusted feedback voltage is applied to the current source; and the current source is configured to control, according to the adjusted feedback voltage, the current output by the current source. By means of the present application, a ramp signal generated by a ramp generator can be adjusted, thereby improving the stability of the ramp signal.
