Abstract
We present a micropower QCIF image sensor fabricated in 0.18μm CMOS technology. Low-power operation is achieved through a system-on-chip design methodology optimizing from device to architecture, yielding a 3-pin autonomous system. Supply voltage and reference are scaled down to 1.0V and 400mV, respectively. Compared to previous work, this imager consumes 42% less energy per pixel.
