摘要
The present invention concerns pulse generators which are powered through movement. Such devices include both implantable medical devices, such as cardiac pacemakers, as well as timepieces such as wristwatches. The present invention particularly concerns a pulse generator which features a full-wave rectifier circuit which has dynamic bias. The full-wave rectifier circuit is implemented using four field-effect transistors (FETs) operable to selectively establish the paths between first and second input terminals and first and second output terminals thereof. Alternating pairs of the diode/FETs are rendered conductive during positive and negative excursions of the input signal to be rectified. Two differential sense amplifiers are associated with two respective ones of the diode/FETs. A dynamic bias circuit is responsive to both positive and negative excursions of the input signal to provide bias current to at least one of the differential sense amplifiers, such that the predetermined threshold amount is substantially less than the threshold of conventional diodes.
