How to realize low-frequency and low-noise bipolar transistor has always been one of the most important topics in the semiconductor field. In this paper, the noise and its model of transistor are briefly analyzed. The way of obtaining low-noise of low-frequency transistor is systematically described. The main performance of low-noise and high-gain transistor of 3DM3 is introduced.
