五、集成电路运算放大器技术发展趋势到目前为止,对于集成电路运算放大器的研制工作,仍然是致力于使其单片集成运算放大器本身的性能尽量接近理想化,如:Z_(in)=∞、A_(v0)=∞、I_(b1)、I_(b2)→0、R_0→0…。在放大倍数一定的情况下,突出地显示出输入阻抗和漂移这两个问题。目前,单片集成运算放大器几乎都是以双极晶体管为基本器件,这是因为它具有工艺较易实现,器件均一
Fifth, the development trend of integrated circuit operational amplifier So far, the development of integrated circuit operational amplifier is still committed to its monolithic integrated operational amplifier itself as close as possible to the ideal performance, such as: Z_ (in) = ∞, A_ (v0) = ∞, I_ (b1), I_ (b2) → 0, R_0 → 0 .... At a certain magnification, the two problems of input impedance and drift are highlighted. Currently, almost all monolithic integrated operational amplifier bipolar transistor as the basic device, it is because it has a process easier to achieve, the device is uniform
