Electromagnetic Receivers TRIZ Cases
- Auto-tunable Optical Transceiver Modules with VOA Calibration
Auto-tunable optical transceiver modules adjust variable optical attenuators using internal signal power comparisons.
- Coherent Receiver Frequency Offset Estimation
A coherent receiver estimates frequency offsets using periodic SYNC bursts to apply phase rotations for data symbol recovery.
- Optical Receiver Calibration Feedback Circuit
Digital feedback circuit adjusts front-end bias points to resolve reference voltage stability issues without extra capacitors.
