Integrated Current and Time References

  • Bob Blauschild


Circuit configurations have been derived to achieve oscillator and filter frequency stability better than 5% over process and temperature variations, without the need for external components, clocking, or trimming. Low temperature-drift current sources can also be realized with this method, which uses MOS threshold and mobility temperature-coefficient cancellation.
