1. A method, comprising:
- configuring a medical device for implantation into a patient, wherein the medical device includes sensing and therapy circuitry interfaced to a controller contained within an implantable housing;
incorporating a temperature sensor for measuring temperature within the implantable housing, wherein the temperature sensor is interfaced to the controller and wherein the temperature sensor utilizes a proportional-to-absolute-temperature (PTAT) current source to generate a temperature signal;
programming the controller to monitor and store temperatures measured by the temperature sensor; and
,programming the controller to either flag or not gather temperature measurements during periods when a capacitor used for delivering electrical therapy is being reformed.
