Analogue/Digital Conversion TRIZ Cases
- Printed Analog Integrator for Low-Cost Perishable Goods Monitoring
Printed analog integration on polymer labels cuts ASIC cost and power while preserving accurate long-term temperature and humidity tracking.
- Grouped Resistor Trimming Circuit for Precise Switchable Resistance
Dividing one adjustable resistor string into groups lowers switch-facing parallel resistance and enables precise trimming from simple code inputs.
- Single-Channel PWM Decoder Circuit for 5 Ns Signal Periods
A capacitor-and-comparator PWM decoder handles 5 ns periods on one channel while maintaining noise-robust duty-cycle decoding.
- Digital ZCS Lock-In Control for Resonant SCC Timing Drift
Real-time zero-crossing tuning keeps resonant switched-capacitor converters synchronized despite component drift, improving charge transfer efficiency.
- Lookup-Table Multi-Level Converter Control for Fly Capacitor Balancing
Precomputed LUT states with a fast flash ADC balance fly capacitor voltages quickly while cutting control delay, IC area, and power.
