TIME TO DIGITAL CIRCUITRY WITH ERROR PROTECTION SCHEME

A time to digital circuit may provide a time measurement of an event, or a time measurement of a duration between multiple events. Various electronic devices may include one or more time to digital circuits. A time to digital circuit may include circuitry to use Thermometer Code for measuring the duration of the time. For example, the time to digital circuit may generate alternating signals using a ring oscillator when receiving an indication of an event. Moreover, the time to digital circuit may convert the alternating signals to a consistent signal with only one transition between high and low signals in multiple consecutive signals. Furthermore, the time to digital circuit may correct erroneous signal values of the consistent signals when multiple transitions between high and low signals in multiple consecutive signals occurs.
