摘要： An antenna sense circuit includes a detector and a level shifter. The detector consists of a voltage drop component, a transistor component, a first resistor component, and a second resistor component. The voltage drop component is coupled between a first power supply and a first terminal of the first resistor component. The second resistor component has a first terminal coupled to a second terminal of the first resistor component and a second terminal coupled to a second power supply. The transistor component has a control terminal coupled to the second terminal of the first resistor component and the first terminal of the second resistor component, a second connection terminal coupled to the first power supply, and a first connection terminal for outputting a first detecting signal. The level shifter adjusts a voltage level of the first detecting signal to generate a second detecting signal.

摘要： The present invention is an electro-absorption modulator with a p-i-n-i-n epitaxy layer whose structure is p-i(MQW)-n+-i(collector)-n to release the trade-off between the operation voltage and the speed, to increase the confinement factor of the light in the un-doped layers, and to reduce the insertion loss caused by the free-carrier absorption in the doped layers, wherein MQW stands for Multiple-Quantum Well.
