A high-accuracy CMOS on-chip RC oscillator
In this paper, a high-accuracy CMOS on-chip RC oscillator (OSC) for MCU application is presented. The oscillator can provide a 16MHz output frequency with the total accuracy in ±1% in all process comer at 1.8v and 55℃ condition, +2% in all process, supply voltage and temperature condition after 7bit digital trimming. This design features low sensitivity to power supply from 1.8v to 6.0v and temperature range from -45℃ to 85 ℃. The on-chip oscillator was fabricated in a 130nm standard digital CMOS process. The final die size is 78umX 132um.Experimental result shows that all performance satisfies the specification.
