10MHz RC oscillator errs ±0.28% over -45 to 125°C

RC oscillators can be small or accurate, and now that can be both after Delft University of Technology*, Silicon Integrated and Tsinghua University revealed a 10MHz RC oscillator with ±0.28% accuracy over -45 to 125°V after a one-point trim, fabricated with a 0.01mm2 footprint in standard 0.18μm CMOS. The scheme avoids needing the need for ...
