Abstract
A switching DC converting device includes a switching DC converter and a synchronous clock circuit. The synchronous clock circuit is used to provide a wobbling synchronous clock input for the switching DC converter, and the central frequency of the wobbling synchronous clock avoids the operating frequency of a circuit powered by the switching DC converter.
Claims18
A switching DC converting device comprising:
- a switching DC converter;
- and
- a synchronous clock circuit configured to provide a wobbling synchronous clock input for the switching DC converter, wherein a central frequency of the wobbling synchronous clock provided by the synchronous clock circuit is synchronous to a phase of and different than an operating frequency of a circuit powered by the switching DC converting device.
A portable system for ultrasonic medical imaging and diagnosing, said portable system comprising:
- a system controller;
- a system receiving circuit;
- a switching DC converter;
- and
- a synchronous clock circuit configured to provide a wobbling synchronous clock input for the switching DC converter, wherein a central frequency of the wobbling synchronous clock is synchronous to a phase of and different than an operating frequency of the system receiving circuit powered by the switching DC converter.
A method for reducing influence of radiation interference noise of a switching DC converter on an ultrasonic receiving circuit in a portable system for ultrasonic medical imaging and diagnosing, said method comprising:
- inputting a wobbling synchronous clock to the switching DC converter;
- and
- operating the wobbling synchronous clock at a central frequency that is synchronous to a phase of and different than an operating frequency of the ultrasonic receiving circuit in the portable system for ultrasonic medical imaging and diagnosing.
