1. A continuous analyte sensor system, comprising: a continuous analyte sensor configured for exposure to a circulatory system of a host and configured to generate a signal associated with an in vivo analyte concentration when the sensor is exposed to a sample of the host; andsensor electronics configured to process the signal, wherein the sensor electronics comprise a fail-safe module configured to detect a malfunction of the system, wherein the fail-safe module is configured to perform a steady state analysis and a transient analysis of the signal and to evaluate a relationship between the stead state analysis and the transient analysis. 2. The system of claim 1, wherein the malfunction comprises an electrical malfunction. 3. The system of claim 2, wherein the electrical malfunction comprises a short circuit. 4. The system of claim 2, wherein the electrical malfunction is associated with at least one of start-up or sensor break-in. 5. The system of claim 1, wherein the malfunction comprises a fluidics malfunction. 6. The system of claim 5, further comprising a flow control system in fluid communication with the sensor, wherein the system is configured to contact at least a portion of the sensor with a sample of the circulatory system, wherein the fluidics malfunction comprises a malfunction of the flow control system. 7. The system of claim 6, wherein the malfunction of the flow control system comprises at least one of a washing malfunction, a sample collection malfunction, a constriction of a component of the flow control system, or a blood clotting on a portion of the sensor. 8. The system of claim 6, wherein the flow control system comprises a vascular access device comprising a lumen, and at least a portion of the analyte sensor is configured to reside within the lumen. 9. The system of claim 6, wherein the flow control system comprises a vascular access device and the analyte sensor is integrally formed with the vascular access device. 10. The system of claim 6, wherein the flow control system is configured to deliver a reference solution into the vascular access device. 11. The system of claim 1, wherein the malfunction comprises a sensor malfunction. 12. The system of claim 11, wherein the sensor malfunction comprises at least one of noise on the signal, drift of a sensitivity, drift of a baseline of the sensor, a broken component of the sensor, blood clotting on a portion of the sensor, or cross-talk. 13. The system of claim 1, wherein the fail-safe module is further configured to perform a waveform analysis of the signal. 14. The system of claim 1, wherein the fail-safe module is further configured to provide at least one of an alert, an alarm or an instruction. 15. The system of claim 14, wherein the fail-safe module is further configured to evaluate a detected malfunction against a criterion. 16. The system of claim 1, wherein the analyte is glucose. 17. A continuous analyte sensor system, comprising: a continuous analyte sensor configured for exposure to a circulatory system of a host and configured to generate a signal associated with a in vivo analyte concentration when the sensor is implanted in the host; andsensor electronics configured to process the signal, wherein the sensor electronics comprise a fail-safe module configured to detect a malfunction of the system, wherein the fail-safe module is configured to perform a stead state analysis and a transient analysis of the signal and to evaluate a relationship between the steady state analysis and the transient analysis.
