A low-cost uncooled infrared microbolometer detector in standard CMOS technology
… well microbolometer
array performance can be improved further by using a low noise preamplifier circuit, even at … Another
advantage of the n-well microbolometers is that the pixels
are thermally isolated due to front-side bulk-micromachining,
however, thermopile detector arrays require extra processing
steps to form silicon islands [10] or electroplated gold lines
[11] for thermal isolation between …
