Description

technical field

[0001] The invention relates to an integrated circuit processing method, in particular to an integrated circuit optimization method of an analog operational amplifier. Background technique

[0002] As circuit design enters the era of deep submicron and system-on-a-chip (SOC, System on a Chip), it is necessary to integrate the digital circuit part and the analog circuit part on the same chip to form an integrated circuit. In the whole integrated circuit design process, the design of the analog circuit part is the most challenging. There are many design parameters, complex performance indicators and multi-objective optimization problems in the design of analog circuits, which become the bottleneck in the design of integrated circuits. In the process of integrated circuit design, chip integration, power consumption, cost, and circuit stability are always contradictory factors. The increase in chip integration directly leads to an increase in power consumption, ...
