发明名称 FILTER CIRCUIT WITH VARIABLE CAPACITANCE FOR USE WITH IMPLANTABLE MEDICAL DEVICES
摘要 An implantable medical device (IMD) as described herein includes an input filter circuit having variable capacitor elements that can be electronically adjusted based upon current operating conditions (such as electromagnetic conditions, noise conditions, and/or environmental conditions). The variable capacitor elements can be adjusted to accommodate pre-designated operating modes of the IMD and/or dynamically in response to changing operating conditions. In one embodiment, the variable capacitor elements are realized using digitally programmable switched capacitor arrangements.
