“…As is evident in the figure, the processing is carried out on one-dimensional (1-D) data obtained by projecting the two-dimension intensity distribution of an image onto the horizontal and vertical axis, and therefore it is quasi two dimensional processing. Such image data projection can be carried out easily using , accessible image sensors like BASIS [20], [21] or CMOS sensors [22]. The sensor output signals are capacitively coupled to a MOS floating gate and accumulated along a single row or a single column, then being read out via MOS source follower configuration.…”

A new-architecture integrated circuit has been developed as a key element of a system that can real-time track the center of mass of an moving image on a two-dimensional (2-D) pixel array. The circuit has been implemented using a high-functionality transistor called neuron MOSFET (neuMOS or MOS for short), hence having a very simple circuit configuration. A quasi-two-dimensional algorithm is assumed for system in the circuit. A one-dimensional (1-D) array of neuron MOS circuits automatically finds the center-of-mass location using the image intensity distribution projected onto x x x or y y y axis. The unique feature of the circuit is that it accepts analog inputs without A/D conversion but produces binary outputs, thus providing a very smooth interfacing between the real world and digital systems. Test circuits have been fabricated by a double-polysilicon CMOS process and their operation has been experimentally demonstrated.Index Terms-Center of mass, neuron MOS, source follower.

“…Particularmente para intensidades luminosas mais baixas, a fotocorrente gerada na junção não é suficiente para polarizar o BJT na região em que o ganho de corrente é significativo. Apesar das dificuldades citadas acima alguns estudos sobre o fototransistor BJT podem ser encontrados na literatura direcionados para aplicações específicas nas quais o processamento analógico no modo corrente é mais adequado[11][12][13][14][15]. A Figura 2.10 ilustra a estrutura dos dois tipos de BJTs disponíveis em processo padrão CMOS: (i) BJT vertical e (ii) BJT lateral.…”
