PROGRAMMABLE CIRCUIT FOR DRIFT COMPENSATION

摘要

Systems and methods relating to programmable circuits are described. Several embodiments relate to systems and methods for controlling the long-term stability and accuracy of circuits that produce waveforms varying in frequency and amplitude. Such embodiments may include a circuit comprising a common vacuum environment that houses a pair of heater-thermocouples. The circuit may compare signals outputted by each heater-thermocouple and then may produce a resultant value based on the comparison. The resultant value may be used by the circuit to control the long-term stability and accuracy of the circuit. Such control of the long-term stability and accuracy of the circuit may include drift compensation associated with certain components of the circuit.
