Abstract
A circuit and design for an analog front end is provided. The AFE includes a number of sub-stages each with multiple optional or alternative pathways to complete the circuit. These pathways can be dynamically set during runtime based on the type of imaging catheter used with the AFE or can be set at manufacturing.
Claims17
An analog front end (AFE) for an intracorporeal image acquisition device, comprising:
- a high-pass filter stage, the high-pass filter stage comprising a plurality of high-pass filters and at least one switch selectable to electrically couple one of the plurality of high-pass filters to an input;
- a gain stage comprising:
- a plurality of voltage attenuators,
- a plurality of amplifiers circuits, and
- a plurality of jumper locations, wherein one or more jumpers are installed in at least one but not all of the plurality of jumper locations to electrically couple one of the plurality of voltage attenuators to an output from the high-pass filter stage and to electrically couple an output from the one of the plurality of voltage attenuators to a one of the plurality of amplifier circuits;
- and
- a low-pass filter stage comprising a plurality of low-pass filters and at least one switch selectable to electrically couple one of the plurality of low-pass filters to an output from the gain stage.

An intracorporeal image acquisition device comprising:
- image acquisition circuitry comprising an analog front end (AFE) and a digital processing circuit coupled to the AFE, the digital processing circuit arranged to receive a digitized signal from the AFE, the AFE comprising:
- a high-pass filter stage, the high-pass filter stage comprising a plurality of high-pass filters and at least one switch selectable to electrically couple one of the plurality of high-pass filters to an input;
- a gain stage comprising:
- a plurality of voltage attenuators,
- a plurality of amplifiers circuits, and
- a plurality of jumper locations, wherein one or more jumpers are installed in at least one but not all of the plurality of jumper locations to electrically couple one of the plurality of voltage attenuators to an output from the high-pass filter stage and to electrically couple an output from the one of the plurality of voltage attenuators to a one of the plurality of amplifier circuits;
- and
- a low-pass filter stage comprising a plurality of low-pass filters and at least one switch selectable to electrically couple one of the plurality of low-pass filters to an output from the gain stage.
