Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0018] see figure 1 and figure 2 , an order-controllable CMOS multi-stage radio frequency rectifier, including 1 basic differential rectification unit, n-1 enabled differential rectification units and n control units. The basic differential rectification unit is used as the first stage of the multi-stage radio frequency rectifier to convert the input alternating current into direct current and supply energy for the subsequent enabled differential rectification unit. n-1 enabled differential rectifying units form the second to nth stages of the multi-stage radio frequency rectifier, and each enabled differential rectifying unit includes 4 rectifying transistors and 1 enabling transistor. The rectifier tube is used to conve...

Abstract

The invention discloses a CMOS multi-order radio frequency rectifier with an order controllable. The rectifier comprises one basic differential rectifying units,n-1 enable differential rectifying units and n control units. Through the accessing of a grounding end control,the shutting power consumption of the rectifier is reduced,the problem of larger shutting power consumption in the prior art issolved,expansion cascading can be conducted on the structure of the rectifier to obtain an n-order rectifier with the order controllable,a function of controllable operating order can be achieved,andtherefore maximum power operation is achieved. By means of the rectifier,the shutting power consumption of the rectifier can be significantly reduced,and a reference scheme is provided for low-power consumption standby of a multi-order rectifier.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to a CMOS multi-stage radio frequency rectifier with controllable order. Background technique [0002] With the rapid development of wireless charging technology, people require devices to maintain high power conversion efficiency (PCE) charging at longer distances. One of the core technologies of wireless charging is the design of the rectifier. Since the wireless signal energy in the space is relatively low, multi-stage rectifiers need to be cascaded to meet the power supply requirements of the equipment. However, too many orders will reduce the PCE, and too few orders will cause the output voltage to fail to meet the power supply requirements of the load. According to the input power (P IN ) and the size of the output voltage, reasonably controlling the order number of the rectifier can realize the multi-stage rectifier to maintain a high PCE when the output ...
