| Abstract: | A novel error-amplifier is presented, which is used in DC-DC converter. Based on the error-amplifier, a system compensation method is introduced. This error-amplifier circuit has implemented with XFAB 0. 6μm CMOS process. According to the simulation result, the power consumption is 1.2-2mW at 2.5-5V power supply, and the gain error is less than 2mV, the transmission delay with no fan-out is 95ns. This error-amplifier is stable in typical application, its phase margin is more than 46. 1°. |
