| Abstract: | The weak signal received by the aerial of receiver in communication systems is usually measured by millivolt.In order to analysis and deal it,the weak signal must be pre-amplified.A kind of weak signal wideband amplifier circuit based on AD603 is designed in this paper as the pre-amplification circuit.The simulation show that the pre-amplification circuit is stable,reliable and excellent in performances. |
