Light Receiving Device Parallel Transfer Transistors

The patent divides the charge transfer function into multiple parallel transfer gates (first transfer gate and second transfer gate) instead of using a single transfer gate. Each gate handles a portion of the charge distribution task, allowing simultaneous operation that effectively doubles the transfer speed while maintaining the required voltage application time for each individual gate.

The patent implements continuous charge transfer by operating multiple transfer gates in parallel simultaneously. While one transfer gate is completing its voltage application and charge transfer, other transfer gates are already initiating their transfer sequences. This overlapping continuous operation eliminates idle time between transfers, maintaining constant productive action without sacrificing the required voltage application duration for reliable transfer.

The patent merges multiple transfer gates and their associated control circuits into a coordinated parallel system. The first transfer gate and second transfer gate operate simultaneously under unified control signals, combining their individual transfer capabilities into a unified high-speed charge distribution system. This merging approach achieves high-speed transfer while keeping the overall circuit architecture relatively simple through standardized parallel design.
