Free running oscillators

Overview

We have a range of free running oscillators for use as watch-dog timers and core clock generators for MCUs and low-power chips with competitive features. These are available off the shelf and in production from 3nm FinFET to 65nm, or custom designed for specific targets. Our oscillators can be optimized for specifications as good as:

Key Features

  • Compact and low power
  • No external components
  • Baseline CMOS logic process masks only
  • Excellent frequency precision over PVT after trimming

Benefits

  • Power < 30uW
  • Accuracy as good as ±1.5% over -40°C to 125°C and Vdd ±10% and product life after trimming for process
  • Period jitter of less than 1%
