摘要： Embodiments of this application disclose a trans-impedance amplifier and a trans-impedance amplifier control method that are used in the field of circuit technologies. A trans-impedance amplifier TIA includes an inverting amplification circuit and a voltage clamping circuit. The inverting amplification circuit is connected in parallel to the voltage clamping circuit. The inverting amplification circuit includes a first PMOS transistor and a first NMOS transistor that have a common gate. A source of the first PMOS transistor is connected to a drain of the first NMOS transistor. The voltage clamping circuit includes a second PMOS transistor and a second NMOS transistor that have a common gate. Gates of the two transistors are connected to an input end of the TIA. A source of the second NMOS transistor and a drain of the second PMOS transistor are connected to an output end of the TIA. The voltage clamping circuit may provide a compensation current to avoid an excessively high or low output voltage of the trans-impedance amplifier. In this way, a voltage difference between the source and the drain of the first PMOS transistor and a voltage difference between the source and the drain of the first NMOS transistor can be controlled, to avoid an over-voltage phenomenon, thereby extending service life of the first PMOS transistor and the first NMOS transistor.

摘要： A method, a system and a device for processing failure is provided; the method is applicable to a label switched path (LSP) including a first node, a second node, and at least one third node. The first node and the second node are adjacent nodes suffering communication breakdown. The first node restarts. The third node is a normal node closest to the restarted first node. When the communication between the first node and the second node is broken, the third node maintains control state information of the LSP in certain time. When the communication between the first node and the second node is recovered in the certain time, the first node, the second node, and the third node recover the control state information of the LSP. A failure processing system and a device on LSP are further provided. Therefore, when several nodes on the LSP suffer communication failures, the LSP can be reliably recovered.
