摘要

叠栅是FinFET技术中最常用的失配敏感电路解决方案之一。提出了一种利用150个短通道器件构成的叠加栅极实现高精度的带隙电路。在目标MOS阵列中加入均匀的周围图案,可以消除密度梯度效应(DGE)引起的器件失配。在低功率RF LNA和VCO中,可以实现直流功耗降低。采用近阈值电压(NTV)设计技术,射频功率进一步降低50%。

Analog/RF wonderland: Circuit and technology co-optimization in advanced FinFET technology
Stacked-gate is one of the most popular solutions used in mismatch-sensitive circuits in FinFET technology. A Bandgap circuit using stacked-gate formed by 150 short-channel devices to achieve high accuracy is demonstrated. Adding uniform surrounding patterns to the target MOS array, the device mismatch caused by DGE (density gradient effect) can be cancelled. In low-power RF LNA and VCO, dc power reductions are achieved. The near-threshold-voltage (NTV) design technique is adopted for further 50% RF power reduction.
