Abstract

An embodiment of the present application provides a hybrid reconfigurable charge pump circuit, the charge pump circuit includes a first link, a second link, a third charge pump and a third link; wherein the first link VCR1=Vx / (A1Vin+A0Vin) in one link, VCR2=(B1Vout+B0Vout) / Vy in the second link, VCR4=Vz / (C1Vin+C0Vin) in the third link , VCR3=(Vx+Vz) / (Vout+Vy) of the third charge pump, and the total VCR5=Vout / Vin of the charge pump circuit, by comparing the input A1, A0, B1, B0, C1, C0 as Logic 0 or logic 1 regulates the signal input by the charge pump circuit, and can obtain VCR5 of various charge pump circuits, which can effectively improve the average efficiency of the VCR5 of the charge pump circuit within the input voltage range, and effectively adjust the charge pump circuit. The fineness of the pump circuit avoids the problem of excessive fluctuations in the efficiency of the charge pump circuit. It solves the technical problems in the prior art that the efficiency fluctuates too much in the input voltage range and the average efficiency is not high.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a hybrid reconfigurable charge pump circuit. Background technique [0002] A DC-DC converter is a type of converter that can convert one DC input voltage to another DC output voltage. The DC-DC converter can increase or decrease the input voltage, and can also generate positive or negative voltage at the output, and is widely used in various power management chips. [0003] Existing DC-DC converters mainly include linear regulators, inductive DC-DC converters, and capacitive DC-DC converters, and capacitive DC-DC converters have advantages in terms of performance, cost, and integration. : First, the capacitive DC-DC converter can realize step-up and step-down, and is suitable for applications with low input voltage and wide variation range, such as energy harvesting chips, while linear regulators cannot realize step-up. Second, capacitive DC-DC converters ...
