| Abstract: | A three-stage trans-impedance amplifier designed in CMOS technology is presented,which stability can be promoted by varying the gain of open loop system.Sensitivity of -25.2 dBm and dynamic range of 26.2 dB at 2.SGb/s are achieved without stability problems for the phase margin between 41.1 to 89.9 degree. |
