Analogue-Digital Converters TRIZ Cases
- Optocoupler Isolation Circuit With Gain-Error Compensation
Time-sequential reference levels let an optocoupler transfer isolated sensor data accurately despite large gain deviation, avoiding factory calibration.
- Power Source Voltage Stabilization Using PID Feedback Control
Closed-loop sampling and PID frequency adjustment stabilize power source output voltage by controlling supply current to reduce fluctuation risks.
- LiDAR Receiver Column Circuits for High-Resolution FPS
Independent receiver column circuits reduce wasted LiDAR pixels, preserving high resolution while improving frame rate.
- Sample-and-Hold Precharging to Reduce AD Conversion Errors
Precharging the sample-and-hold capacitor cuts charge-sharing delay in the filter stage and suppresses AD conversion errors.
