提出了一种基于细胞的前向体偏置技术来抑制整体工艺变化，并给出了该技术的设计流程。即使在电源电压为1.2 V且面积开销小的情况下，嵌入式电流源单元和限制单元也保证了无锁存操作。通过将该技术应用于媒体处理器，在不牺牲最大泄漏规格的情况下，最坏情况延迟减少了20%。
A cell-based forward body-biasing technique to suppress the global process variation and its design flow are proposed. Latch-up free operation is guaranteed by embedded current source cells and limiter cells even when supply voltage is 1.2 V with small area overhead. By applying this technique to a media processor, the worst-case delay is reduced by 20% without sacrificing the maximum leakage spec.
