Patent ID: 11933823
Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G

Claim 9:
10. A device to compare voltages, the device comprising:
amplitude analysis circuitry configured to:
receive an input voltage;
generate a comparator signal based on the input voltage to a reference voltage;
update the reference voltage based on the comparator signal; and
provide an indication of the reference voltage to processor circuitry;

time to digital converter (TDC) circuitry configured to, responsive to a determination that the comparator signal indicates the input voltage is greater than the reference voltage, increment a counter value;
TDC analyzer circuitry configured to provide the counter value to the processor circuitry; and
the processor circuitry configured to detect an anomaly based on one or more of the reference voltage and the counter value.
