The PW2053 is a high-efficiency monolithic synchronous buck regulator using a constantfrequency, current mode architecture. The device is available in an adjustable version. Supply currentwith no LOAD is 40uA and drops to <1uA in shutdown. The 2.5V to 5.5V input voltage range makesthe PW2053 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provideslow dropout operation, extending battery life in portable systems. PWM/PFM mode operationprovides very low output ripple voltage for noise sensitive applications. Switching frequency isinternally set at 1.2MHz, allowing the use of small surface mount inductors and capacitors. Lowoutput voltages are easily supported with the 0.6V feedback reference voltage

全文将用一个贯穿始终的例子来说明如何绘制版图。这个例子绘制的是一个最简单的非门的版图。S2-1建立版图文件使用library manager.首先，建立一个新的库myLib，关于建立库的步骤，在前文介绍cdsSpice时已经说得很清楚了，就不再赘述。与前面有些不同的地方是：由于我们要建立的是一个版图文件，因此我们在technology file选项中必须选择compile a new tech file，或是attach to an exsiting tech file。这里由于我们要新建一个tech file，因此选择前者。这时会弹出LOAD tech file的对话框，如图2-1-1所示。在ASCII Technology File中填入csmclo0.tf即可。接着就可以建立名为inv的cel了。为了完备起见，读者可以先建立inv的schematic view和symbol view（具体步骤前面已经介绍，其中pmos长6u，宽为0.6u。nmos长为3u，宽为0.6u。model仍然选择hj3p和hj3n）。然后建立其layout view，其步骤为：在tool中选择virtuoso-layout，然后点击ok。
