—A CMOS image sensor which is capable to simultaneously sense an optical and an op-chip potential image was designed and fabricated. The sensor was designed with target applications to sense neural activities and DNA spots in on-chip configuration. We designed compatibly configured light sensing pixel and potential sensing pixel. The pixel size is 7.5 µm. A(More)
— For wide dynamic range, compatibility with digital circuits, and low-voltage operation, the pulse modulation technique is suitable for an implanted bioimage sensor. We demonstrate bio-fluorescence imaging of the hippocampus in a sliced mouse brain using a pulse modulation-based image sensor. The sensor architecture and system configuration are discussed.(More)
