| Abstract: | Active filters are often used in pcecision measuring instruments of petroleum and geology exploration. Error source analysis and electronic circuit design of active filters are quite tough problems for designer. If not well solved,it will affect the pcecision of these instruments,sometimes even lead to the failure of normal oprations. The paper mainly expounds the amplification and band-width of operational amplifiers used in active filters,the slope and output resistance and the offset design of operational amplifers as well as noise suppression etc. |
