Engineering Contradiction Analysis
1Adaptability or versatility
If traditional general-purpose digital control chip is used, then digital control functions are achieved, but extensive external analog circuitry is required
Solution Approach 1:
The patent combines digital control modules with analog modules (comparator, DAC, amplifier, ADC) into a single integrated chip. This merging eliminates the need for extensive external analog circuitry while maintaining digital control functionality, directly resolving the contradiction between digital control capability and external circuit complexity.
Solution Approach 2:
The integrated chip is designed to perform multiple functions including digital processing, analog signal comparison, digital-to-analog conversion, analog signal amplification, and analog-to-digital conversion. This multi-functionality allows a single chip to replace what previously required separate digital and analog components, reducing overall system complexity.
