This brief presents an input buffer based on AC-coupled flipped source follower (SF) for a 12-bit 8-GS/s time-interleaved (TI) ADC. The flipped SF can drive the ADC’s sampling capacitance with high ...

This study reports the first ever 3-wafer-stacked CMOS image sensor comprising an artificial intelligence (AI) chip with a deep neural network (DNN)-based circuit. The sensor was fabricated by bonding ...
