Analogue/Digital Conversion TRIZ Cases
- Offset Compensation Circuit With Thermal-Matched Current Injection
Thermal-matched current injection cancels differential-pair offset voltage, cutting temperature drift without increasing silicon area.
- Circuit for voltage offset compensation
Temperature-matched current injection trims differential pair offset while reducing drift, improving analog comparator and op-amp accuracy.
- Resolver Decoder Hardware Filtering for Real-Time Shaft Angle Estimation
Hardware FIR filtering and rectification cut CPU load and cost while preserving accurate real-time resolver shaft angle estimation.
- Reference Voltage Buffer With Active Loads for Fast Settling
Active-load reference buffering speeds ADC settling while matching PVT behavior to keep comparator reference voltages stable.
- Signal Strength Detector Calibration Using On-Chip Temperature Drift Control
On-chip heaters, PTAT current adjustment, and regression-based settings calibrate signal strength detectors faster across temperatures.
- Class-D Amplifier Circuit With Current-DAC Common-Mode Control
A current-type DAC adjusts common-mode voltage in a Class-D amplifier, cutting filter noise and improving response speed.
