Abstract

The invention provides an integrated circuit design method and system based on gm / ID lookup table. The method includes the following steps: 1, obtaining simulation data of various parameters of the integrated circuit operation by using a simulation tool; 2, processing the simulation data of each parameter, obtaining the relationship among the parameters, and importing the simulation data into a table with searching function; Step 3, making an analog circuit design table through the table lookup method of the table with the lookup function, and generating an integrated circuit according to thedata in the analog circuit design table. A method and system for integrate circuit design based on GM / ID look-up table utilize GM / ID method to process data, Establish lookup table, make design table of various analog circuits, input target parameters can get design results, in the design process do not need to carry out circuit simulation, greatly improve efficiency, save time and energy, can be widely used in industrial design.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to an integrated circuit design method and system based on gm / ID table lookup. Background technique [0002] F.Silveira, D.Flandre and P.G.A.Jespers published the gm / ID method on JSSC in 1996. Using the gm / ID method for design is a more accurate method, which has been used by Stanford University and the University of California, Berkeley. conduct teaching and research. The gm / ID method not only takes into account the small-signal parameters and large-signal parameters in the determination of different transistor dimensions, but also allows a unified and comprehensive research method in all transistor operating regions, helping to simplify the design process of analog circuits. [0003] gm / ID is more convenient to use than VOV when used as a design parameter. First of all, gm / ID is directly related to the performance parameters of the circuit, such as gain, cut-off frequenc...
