A new architecture using a half-rate clock for pseudo-random-bit-sequence (PRBS) generator has been devised for high-speed and low-power operation. For proof of concept, a 27−1 PRBS generator IC was designed and fabricated with 290-GHz-fT InP HBT technology. The PRBS generator operates up to 100 Gbps with a low power consumption of 955 mW, leading to a record figure-of-merit of 1.42 mW·Gbps−1. This...
We propose real-time heterodyne imaging interferometry using the three-phase correlation image sensor (3PCIS). The 3PCIS produces temporal correlation between incident light intensity and three-phase reference signals at each pixel and outputs the results as images in every frame. This property enables simultaneous demodulation of amplitude and phase images of heterodyne interference within a single...
