Abstract (en)
[origin: WO9521412A1] On an integrated circuit (230), a back-up oscillator circuit (231) is provided which includes a back-up oscillator (540) which can be fabricated using conventional integrated circuit techniques, a clock monitor (520) for sensing a malfunction in a primary oscillator, and a multiplexer (530) for switching from the primary oscillator to the back-up oscillator (540) in the event the primary oscillator malfunctions. The back-up oscillator (540) is typically used in an anti-lock braking system to provide a safe shutdown after an oscillator malfunction. The internal back-up oscillator (540) being sufficient for execution of a shutdown routine.
