Intelligent self-adaption driving stage control system and method of integrated circuit chip

Abstract

The invention discloses an intelligent self-adaption driving stage control system of an integrated circuit chip, comprising a chip drive circuit, a chip output circuit, a signal detection circuit and a control logic circuit, wherein the chip drive circuit or the chip output circuit outputs a feedback signal to be connected to the input end of the signal detection circuit; the signal detection circuit samples and compares the feedback signal so as to output a detection result signal to be connected with the first input end of the control logic circuit; the control logic circuit outputs a control signal to the chip drive circuit according to the detection result signal. The invention also provides an intelligent self-adaption driving stage control method of an integrated circuit chip, which can automatically adjust chip driving capability and can cope with the situation of insufficient driving capability, thus ensuring that the same chip can cope with different loads so as to reduce the amount and types of needed chips as well as lower the production and design cost of manufactures; in addition, the chip is easy to apply, and the invention can deal with extra strong driving capability, and saves more power and electricity.

Description

technical field [0001] The invention relates to the field of integrated circuit chips, in particular to a system and method for intelligent self-adaptive driving stage control on integrated circuit chips. Background technique [0002] Integrated circuit chips generally need to be connected to the load or other devices or chips equivalent to the load in the application. The driving capability of the chip represents whether the chip can support a lot of loads, and whether it can provide enough current, voltage or power to the rear. The ability to support the normal work of the level. The driving capability of the chip directly affects the function of the chip itself, affects whether the chip can be fully utilized in the circuit, and even affects whether the entire circuit system can operate normally according to the design. [0003] The greater the load connected to the chip, the higher the requirement for the chip's drive capability. If the next level of a chip with a speci...

Therefore, the increase in load capacitance will cause the signal to rise and fall slowly, making the chip drive capability insufficient

[0004] In the above two cases, the current practice of the chip industry is to design chips with greater drive capabilities to cope with large loads, otherwise the load can only be reduced. Then, it is necessary to design chips with different sizes of drive capabilities to cope with various This increases the number and types of chips required, increases the manufacturer's production and design costs, and increases the difficulty of using the chips.
