Latest Patents
One of Jianhai Yu's latest patents is a "High-speed transimpedance amplifier with bandwidth extension feature over full temperature range and bandwidth extension method." This invention solves the problem of boosting core amplifier bandwidth technology across a full temperature range. It includes a preamplifier TIA, a phase splitting stage PS, a pre-driver stage Pre-Drive, an output buffer BUFF, and an offset cancellation circuit OC. The preamplifier TIA utilizes gate-drain voltage cancellation technology to expand bandwidth, achieving a -3 dB bandwidth greater than twice the closed-loop bandwidth of the first-order TIA. The pre-driver stage is designed to drive the output buffer, compensating for bandwidth differences under varying temperature conditions.
Another notable patent is the "High-speed optical transceiver integrated chip drive circuit with phase delay compensation function." This invention features a transmitting end drive circuit that drives a laser to emit light for signal transmission and a receiving end drive circuit that optimizes signal degradation. It includes long code phase lead and lag adjustment circuits to address the differences in group delay and phase delay for high-speed signals after passing through the backplane.
