摘要
开关稳压电源具有集成度高、外围电路简单、电源效率高等优点,在各种电子产品中得到广泛的应用。
论文中采用0.5μm CMOS工艺,使用Cadence EDA中的Composer包及Spectre仿真工具,设计了一种DC-DC开关电源控制芯片。采用电流模式PWM控制,正常的工作频率为700KHz/1.2MHz,脉宽调制信号的最大占空比为85%。
论文中首先介绍了DC-DC转换器的基本原理。然后,根据功能需要进行了电路的总体结构设计。再对电路的主要功能子模块电路进行了详细分析,使用设计软件Cadence Composer和Spectre工具对子模块电路进行了设计和模拟仿真,给出了仿真数据,主要模块电路的电特性参数均可达到设计要求。最后,对整体电路进行了联合仿真,模拟结果表明该电路完成了设计功能、达到了预先制定的设计要求,进而采用Cadence下的Virtuoso Layout Editor工具进行了版图设计,并通过了CSMC 0.5μm工艺DRC和LVS的版图验证。
Switching regulators have been widely used in both consumer and industrial electronic products for its highly integrated level, fewer peripheral components and high efficiency.
A 0.5μm CMOS technology, Composer and Spectre tools of Cadence EDA are used, a single DC-DC chip is designed. It works at 700KHz/1.2MHz with current mode pulse width modulation and the PWM maximum duty is 85%.
In this dissertation, the principle of DC-DC converter is given firstly. Then, the circuit modules are designed according to its function requirements. Circuits are designed and stimulated with Cadence Composer and Spectre tools. The results illustrate that the requirements of the functional designs can be met. At last the whole design is simulated and shows that the desired functions and performances are achieved. The layout is completed with virtuoso layout editor, and the DRC, LVS are performed by CSMC 0.5μm process.
