Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single capacitor is used to generate triangular-wave signal, then the device structure is simple, but the signal generation accuracy deteriorates due to voltage-dependent capacitance
Solution Approach 1:
The capacitor is divided into two separate capacitor elements (first capacitor element and second capacitor element) connected in parallel. Each capacitor element has different capacitance characteristics that compensate for the voltage-dependent capacitance effect when used together, thereby improving triangular-wave signal generation accuracy while maintaining relatively simple device structure.
2Measurement precision
If capacitor elements with different capacitance values are used, then the triangular-wave signal generation accuracy is improved, but the device complexity increases
Solution Approach 1:
Two capacitor elements with different capacitance characteristics are combined in parallel configuration. The first capacitor element has capacitance C1 and the second has capacitance C2, where C1 ≠ C2. When charged and discharged together, they generate a triangular-wave signal with improved accuracy for analog-to-pulse conversion, while the parallel connection keeps the overall structure manageable.
