摘要

本文介绍了一种在$0.25~\mu \ mathm {m}$进程中实现偏移抵消的片上振荡器。通过在单个比较器中自动选择参考电压，所提出的振荡器可以完美地实现偏移抵消。此外，它将比较器计数从两个减少到一个，以节省面积和节省电力。仿真结果表明，在-40 ~ 90~ {\circ} \math {c}$范围内，温度系数为2.3 ppm/oC，而在30 kHz时消耗6.5~\mu W$。

An On-Chip Oscillator with Comparator Offset Cancellation

This work presents an on-chip oscillator with offset cancellation in $0.25~\mu \mathrm {m}$ process. By automatically choosing the reference voltage in a single comparator, the proposed oscillator can perfectly achieve offset cancellation. In addition, it reduces the comparator count from two to one for area-saving and power-saving. The simulation results exhiUit a Temperature Coefficient of 2.3 ppm/oC from -40 to $90~^{\circ} \mathrm {c}$ while consuming $6.5~\mu W$ at 30 kHz.
