High-speed steady-state optocoupler

The invention belongs to the technical field of semiconductor devices, and particularly relates to a high-speed steady-state optocoupler, a transimpedance amplifier circuit A101 outputs signals to a signal processing circuit A102, the signal processing circuit A102 comprises a time sequence generation circuit B1021 and a time sequence trigger circuit B1022, and the high-speed steady-state optocoupler solves the technical problems that in the prior art, when the power consumption of a transimpedance amplifier TIA is high, much heat and extra noise can be generated, and the power consumption of the transimpedance amplifier TIA is low. Therefore, the problems of low transmission rate and low performance and stability are solved, and the technical effects that the transmission rate is compensated, electrical isolation can be completely realized, and the anti-interference capability is strong are achieved. 本发明属于半导体器件技术领域，尤其涉及一种高速稳态光耦，跨阻放大电路A101输出于信号处理电路A102，信号处理电路A102包括时序发生电路B1021和时序触发电路B1022，本发明解决现有技术存在当跨阻放大器TIA功
