Abstract

The invention discloses a method for improving transmission characteristics of a fixed-length bonding wire. The method comprises the following steps: establishing a bonding wire simulation model, extracting model distribution parameters, fusing the extracted distribution parameters into a five-order Chebyshev low-pass filter prototype; and completing the design of the microstrip line filter by using the ADS according to the prototype parameters of the filter, performing optimization design through an ADS optimization control until the design requirement is met, and importing the design resultinto the HFSS to perform simulation design by using a bonding wire model to obtain a final simulation result. When the length of the bonding wire is fixed, the transmission characteristic of the bonding wire interconnection circuit can be remarkably improved, and the bonding wire interconnection circuit has the advantages of being simple in design thought, easy to implement, wide in frequency bandwidth and capable of being applied to any bonding wire.

Description

technical field [0001] The invention relates to the technical field of electronic engineering, and further relates to the interconnection between chips and transmission lines in a microwave multi-chip module. Background technique [0002] With the continuous pursuit of the miniaturization of microwave circuits, multi-chip assembly technology is an effective way to realize the miniaturization of microwave circuits. In microwave multi-chip modules (MCM), bonding wire is still widely used in actual production due to its simple process and low price, and has become a key technology to realize the electrical interconnection of microwave multi-chip modules. As the frequency of the signal increases, the bonding wire presents a high impedance state due to its parasitic parameters and skin effect, causing signal integrity problems in signal transmission. Therefore, in microwave circuit design, it is very important to analyze, optimize and design the parasitic characteristics of bond...
