....computation to zero rather than matching the photoreceptor outputs and balancing the spatial derivative circuit. Using the floating gate auto zeroing amplifier described by Hasler et al. 18] a 138 Pesavento et al. spatial derivative circuit currently being used in other projects [19,20] was modified to dramatically reduce offset errors, or equivalently, to increase the dynamic range. This circuit uses a combination of electron tunneling to reduce charge and hot electron injection to increase charge on the transistor gate. 2. Circuit Description The circuit previously used to ....
....to reduce the effects of circuit offsets, it manifests itself as a dead zone in the spatial derivative transfer characteristics. Other configurations of the pair of stacked mirrors to compute the polarity or the absolute value of the bipolar current have been presented in the literature [19,20]. The new circuit that we present is shown in Fig. 1(b) The pFET differential pair is, in this case, terminated through a pair of diode connected transistors. The diode connected transistor on the right is the input to a current mirror which constitutes the input to the inverting auto zeroing ....

....the circuits, one can resort to multi chip systems [7] For such systems the limited number of the chips input output ports requires time multiplexing of the communication channels. If the vision chips transmitting data have sparse pixel activity, as is often the case with adaptive silicon retinas [9], sequential multiplexing techniques make inefficient use of the communication channel bandwidth [13] Asynchronous event based communication, on the other hand, represents a very efficient communication protocol for multi chip neuromorphic systems [2, 11] The most popular representation used for ....
