Abstract

The embodiment of the invention provides a hybrid reconfigurable charge pump circuit. The charge pump circuit comprises a first link, a second link, a third charge pump and a third link, wherein VCR1in the first link is equal to Vx / (AVin + A0Vin), VCR2 in the second link is equal to (BVout + B0Vout) / Vy, VCR4 in the third link is equal to Vz / (CVin + C0Vin), VCR3 of the third charge pump is equal to (Vx + Vz) / (Vout + Vy), the total VCR5 of the charge pump circuit is equal to Vout / Vin; signals input by the charge pump circuit are regulated and controlled by setting the input A, A0, B, B0, C andC0 to be logic 0 or logic 1; the VCR5 of various different charge pump circuits can be obtained, the average efficiency of the VCR5 of the charge pump circuit in the input voltage range can be effectively improved, the fineness degree of the charge pump circuit is effectively adjusted, and the problem that the efficiency fluctuation of the charge pump circuit is too large is avoided. The technicalproblems that in the prior art, efficiency fluctuation within the input voltage range is too large, and the average efficiency is not high are solved.

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 ...
