一、高稳定度集成稳压电源设计XWY-8型集成稳压电源是一种具有极高稳定度的中规模线性集成电路。该电路是作者与袁贞丰同志合作设计,与691厂合作研制成功的。在这个集成块的线路中,采用了不对称输入阻抗的双端输出差分放大器,零温漂基准电路和动态内阻极大的恒流源电路;版图设计和工艺参数选择有两个重要特点:一是恒流源电路中横向PNP管的动态内阻很大,因而恒流性能极好;二是集成块外延层电阻率取得了
First, the high stability of the integrated power supply design XWY-8-type integrated power supply is a very high stability of the scale of linear integrated circuits. The circuit is designed by the author and Yuan Zhenfeng comrades in cooperation with the 691 plant successfully developed. In this integrated circuit line, using asymmetrical input impedance of the double-ended output differential amplifier, zero temperature drift reference circuit and a very large dynamic resistance constant current source circuit; layout design and process parameters have two important characteristics: First, the constant current source circuit lateral PNP tube dynamic resistance is very large, so constant current performance is excellent; Second, the resistance of the integrated block epitaxial layer made
