  • A CMOS Active Pixel Image Sensor with In-pixel CDS for High-Speed Cameras (.pdf)
    by the CDS combined with the charge-transfer amplifier. The total number of devices in the pixel is 11 transistors and 2 MOS capacitors. Test circuits were fabricated using a 0.25µm CMOS process. The sensitivity of the 20 x 20µm2 pixel using the floating diffusion capacitor of 6.2fF
  • Shunt Regulator Operation (.pdf)
    A shunt regulator is an electrical device used in motion control systems to regulate the. voltage level of the DC bus supply to protect the amplifier, motor, and other components. in the system from an over-voltage condition. The bus voltage level can increase if excess. energy flows back through
  • Sensor Sense: Passive Infrared-Motion Sensors
    include galliumnitride, caesium nitrate, and lithium tantalate. Skin temperature is approximately 34 C, typically higher than background temperatures. As a person walks past the sensor, their higher skin temperature creates a greater charge in the pyroelectric material. An amplifier circuit boosts
  • Single electron toggles transistor on and off
    signal, Vac, superimposed on a dc bias voltage, V. The circuit detects the net current, , with a current amplifier. The third electrode, G, is floating. The device, dubbed the single-electron transistor (SET) by its developers Robert Blick at the University of Wisconsin-Madison and Dominik Scheibe
