Researchers at NASA’s Johnson Space Center (JSC) have patented a compact circuit design that does not require the use of external components. The design allows for the construction of multi-pole low pass filters for multiple instrument channels on a single complementary metal-oxide-semiconductor (CMOS) chip. The system does not require external components, such as capacitors, which add bulk and noise. In addition, the high performance circuit improves upon several challenges posed by conventional circuits, which often have significant power drain and cumbersome design. This type of compact system with many sensors could be used in space-constrained applications such as a small spacecraft or robot. JSC has received patent number 6,943,619 for this technology.
