摘要

提出了一种采用两个片上数字校准电路维持环传递函数的容PVT锁相环结构。采用90nm CMOS工艺制作了9种条件下的测试芯片,分别是电阻和电容。实验结果表明,在任意PVT条件下,相位噪声在10 MHz偏移范围内保持+ 2dBc/Hz。

A PVT Tolerant PLL with On-Chip Loop-Transfer-Function Calibration Circuit
A PVT tolerant PLL architecture which uses two on-chip digital calibration circuits to maintain loop transfer function is presented. Test chips with 9 conditions, MOSes, resistors and capacitors, were fabricated in a 90 nm CMOS technology. Experimental results show that the phase noise remains + 2dBc/Hz within 10 MHz offset under any PVT condition.
