A SiPM-based VLC Receiver for 3.45 Gigabits/s Communication Using OOK Modulation
International Conference on Intelligent Pervasive Computing, 2020 Results are presented which show that by using a SiPM with a higher maximum output pulse rate it is possible to increase the highest maximum OOK data rate ever achieved at a BER of 10-3 from 2.4 Gbits/s to 3.45 Gbits/s.

CMOS OOK modulator with fast envelope transient
Electronics Letters, 2019 This Letter presents a 2 GHz 130 nm CMOS absorptive on–off keying (OOK) modulator. The loop matching technique is proposed to realise wideband matching such that fast modulation envelope transient can be achieved. The parallel LC network is adopted to reduce the impedance variation between ...
