DRIVE APPARATUS AND DISTANCE MEASUREMENT SENSOR INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17984043 titled 'DRIVE APPARATUS AND DISTANCE MEASUREMENT SENSOR INCLUDING THE SAME
Simplified Explanation
The patent application describes a drive apparatus for an optical device, which includes several circuits to generate signals and currents for driving the device.
- The preprocessing circuit performs preprocessing on an input signal to generate a first reference signal.
- The drive circuit generates a driving current for the optical device and also generates a replica current based on the driving current.
- The calibration circuit generates a replica voltage signal based on the replica current. It then changes the phase of the first reference signal based on the replica voltage signal to generate a driving signal, which is provided to the drive circuit.
Potential applications of this technology:
- Optical communication systems
- Optical sensing devices
- Optical data storage devices
Problems solved by this technology:
- Provides a more efficient and accurate drive apparatus for optical devices.
- Allows for better control and adjustment of the driving signal.
Benefits of this technology:
- Improved performance and reliability of optical devices.
- Enhanced signal quality and accuracy.
- Simplified drive apparatus design.
Original Abstract Submitted
Provided is a drive apparatus configured to drive an optical device. The drive apparatus includes a preprocessing circuit configured to generate a first reference signal by performing preprocessing on an input signal; a drive circuit configured to generate a driving current for driving the optical device, and generate a replica current based on the driving current; and a calibration circuit configured to generate a replica voltage signal based on the replica current, generate a driving signal by changing a phase of the first reference signal based on the replica voltage signal, and provide the driving signal to the drive circuit.
