We present a bio-inspired readout integrated circuit (ROIC) for visible and infrared image sensors. At the system level, the architecture relies on an event based readout scheme where only pixels within a programmable range of photon flux rates are output. At the pixel level, a one bit oversampled analogto-digital converter together with a decimator allows(More)
We analyze the traditional analog ROIC architecture and an oversampled &#x03A3; - &#x0394; modulator/decimator architecture. We show how the latter has superior characteristics i.e. an improved maximum signal to noise ratio (SNR<inf>MAX</inf>). This is a result of effectively increasing the well capacity by a factor equal to the oversampling ratio (OSR). We(More)
