毕业设计（论文）--Bi-CMOS集成运算放大器的电路分析及版图设计 Subject: Analysis and layout design of CMOS integrated OP Abstract Integrated operational amplifier is an important electronic components, it is used in electronic applications is very extensive currently, for example, it can be used as amplifiers, comparators, filters, etc. The ideal amplifier should without noise, has infinite gain and input impedance, infinite output impedance and zero offset voltage. In this paper, I mainly study the works of the op amp circuit principle and layout design, and also study briefly the solution of the Bi-CMOS process steps. The op amp circuit including the input stage, bias circuit, the middle stage and output stage. The input signal is loaded into the input stage and output stage amplifies the signal in the right bias. Layout design main is familiar with the design rules, the layout wiring reasonable and beautiful, and must carry on the DRC validation and LVS verification. Bi-CMOS technology to meet the requirements of modern LVSI device performance, especially suitable for high voltage and high current power circuit, there is great potential in future high performance integrated circuits. By the graduation project, I completed a gain of 86dB; the output common-mode range is 3.5V, the offset voltage of 6.5mV, smaller slew rate amplifier circuit design. Map out the territory of the amplifier, and through the DRC verification and LVS verification.
