Abstract

We present a microcontroller having a 0.5 /spl mu/A standby current on-chip regulator. To save regulator area, we propose a dual-reference scheme in which one voltage reference circuit is provided for active mode and another voltage reference circuit is provided for standby mode. The dual-reference scheme reduces regulator area by 50% compared with a conventional scheme in which one voltage reference circuit is commonly used both in active mode and standby mode.

具有0.5 /spl mu/A备用片上电流调节器的双参考方案的低功耗微控制器

我们提出了一种具有0.5 /spl mu/ a备用片上电流调节器的微控制器。为了节省稳压器面积，我们提出了一种双基准电路方案，其中一个电压基准电路用于有源模式，另一个电压基准电路用于待机模式。双基准电路方案与传统方案相比，减少了50%的稳压面积，在传统方案中，一个电压基准电路通常用于主动式和待机模式。
