Abstract: A 256-channel single-photon avalanche diode (SPAD) line sensor was designed for time-resolved Raman spectroscopy in 110-nm CMOS technology. The line sensor consists of an $8\times256$ SPAD ...

Abstract: A planar broadband phase shifter with wide range of differential phase is proposed. To achieve this performance, the design uses quarter wavelength parallel coupled lines combined with two L ...
