Robust circuitry for passive fundamental components

A method for increasing fault tolerance with passive fundamental components, the method comprising:

• routing current to a terminal of at least one passive fundamental component;
• refreshing a voltage level associated with the terminal;
• resetting a flip-flop coupled to the terminal;
• detecting the voltage level associated with the terminal after the routing, the refreshing, and the resetting;
• producing a voltage value based on the voltage level, the voltage value indicative of whether the at least one passive fundamental component is faulty;
• disconnecting the at least one passive fundamental component based on the voltage value;
• and
• connecting at least one redundant passive fundamental component based on the voltage value.

An apparatus comprising:

• at least one passive fundamental component comprising at least one inductor;
• at least one redundant passive fundamental component comprising at least one redundant inductor;
• and
• fault tolerant circuitry coupled to the at least one inductor and the at least one redundant inductor, the fault tolerant circuitry comprising:
• fault detection circuitry configured to detect a fault of the at least one inductor;
• and
• component repair circuitry configured to disconnect the at least one inductor based on the fault.

An apparatus comprising:

• a phase-locked loop comprising:
• at least one passive fundamental component;
• and
• at least one redundant passive fundamental component;
• and
• fault tolerant circuitry coupled to the at least one passive fundamental component and the at least one redundant passive fundamental component, the fault tolerant circuitry comprising:
• fault detection circuitry configured to detect a fault of the at least one passive fundamental component;
• and
• component repair circuitry configured to disconnect the at least one passive fundamental component based on the fault.
