Solid-State Imaging and Biomedical Applications Chairman
James D. Plummer · 1979
In this session, reports on two topical technologies will be presented. Efforts to obtain high resolution, broad spectral sensitivity, high speed and improved signal-to-noise ratio in sotid-state sensors, have been reported at ISSCC. Latest results in these areas will be covered in a pair of introductory papers, the first describing a large single chip imager incorporating an integrated color filter. This device makes possible a single-chip color camera with acceptable resolution and will be shown to have good color separation. Two CCD line imaging devices, affording substantial improvements in performance and ease of use of such devices, will be covered in the following presentation. The development of custom ICs and transducers for biomedical applications will be discussed in the second group of four papers. The biomed systems place severe requirements on power dissipation and power supply voltages since they are, in general, battery powered. The technologies and circuit designs used in these systems have much broader implications, however, because of the increasing use of batten/ power in a wide range of consumer and military electronic systems. This aspect is reflected in a paper that will describe an etched diaphragm pressure sensor which incorporates signal processing circuitry on the thinned diaphragm and requires but two leads. Another effort will detail a custom bipolar circuit useful in a wide range of telemetry systems, since it functions as a multiplexer and signal processor for a number of physiological sensors. Current efforts in pacemaker development include making such devices externally pro. grammable. A custom CMOS chip which provides this capability will be described. In the final paper a complex custom CMOS chip which contains both analog and digital circuitry will be described. This integrated circuit contains all of the essential functions needed for the external measurement of heart rate.
