Solution Overview
Problem
Semiconductor integrated circuit devices suffer from undesired anti-resonance phenomena, leading to significant amplitude drops in signal oscillations at specific frequencies, which negatively impact system performance.
Innovation Solution
A semiconductor integrated circuit device is designed with a damper and a passive component, where the damper is coupled between the chip main circuit and the passive component to suppress anti-resonance, and the damper's resistance is adjustable to optimize anti-resonance suppression, implemented using a variable resistor or transistors in parallel, controlled by a processor to determine the optimal resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a passive component (such as a capacitor) is directly coupled to the chip main circuit, then the system can provide power decoupling and filtering functions, but anti-resonance occurs at specific frequencies causing impedance to increase enormously and signal amplitude to drop
Solution Approach 1:
The patent introduces a damper as an intermediary component coupled between the passive component and the chip main circuit. This damper acts as a mediator that suppresses the anti-resonance phenomenon occurring between the passive component's capacitance and the PCB's inductance, thereby preventing impedance peaks and signal amplitude drops at specific frequencies while maintaining the power decoupling function.
2Reliability
If the damper's resistance is fixed, then the circuit structure is simple, but the anti-resonance suppression effectiveness cannot be optimized for different operating conditions
Solution Approach 1:
The patent implements a variable resistance damper whose resistance value can be dynamically adjusted based on operating conditions. This dynamic adjustment allows the damper to optimize anti-resonance suppression effectiveness under different frequency conditions and loading scenarios, transforming a static component into an adaptive element that responds to system requirements.
Solution Approach 2:
The patent changes the resistance parameter of the damper from a fixed value to a variable value that can be adjusted according to system needs. By modifying the resistance parameter dynamically, the system can adapt to different operating conditions and optimize the suppression of anti-resonance across various frequency ranges and power consumption levels.
