A 2.2-mW 24-Mb/s CMOS LiFi receiver system-on-a-chip with ambient light rejection and post-equalization

A Review on LiFi Network Research: Open Issues, Applications and Future Directions

“…A high reverse bias is added to raise the electric field and the velocity of the carriers responsible for the avalanche effect. Owing to the phenomenon of avalanches, APD shows great photo sensibility relative to a PIN PD, (iii) SPADs, (iv) CMOS sensors [159,[171][172][173] and (v) solar photovoltaic PV cells [156,161,174]. Several benefits and drawbacks of using a PV-based receiver are shown in Table 3.…”

66‐3: Micro‐LED Display with Simultaneous Visible Light Communication Function

“…The subsequent main amplifier further amplifies the received signal, which is then connected to the baseband unit through a digital buffer (BUF) for data recovery. On-chip LDOs are utilized to suppress supply noise effects on the sensitive input stages [5]. Implemented in a standard 0.18-µm CMOS process, the SoC provides a trans-impedance gain of 124 dBΩ within a -3-dB…”

“…The photograph of the receiver SoC is shown in Fig. 4 (b), which occupies a silicon area of 0.7×0.4 mm 2 [5].…”

“…However, the received data was processed off-line. In this paper, we demonstrate the first real-time smart µLED display system for text message broadcast by employing a VLC receiver system on-a-chip (SoC) [5] and a baseband unit to detect the transmitted text messages from the µLED display, and thus physically verify the concept of a smart display. The achieved VLC bit rate is 2 Mb/s at a distance beyond 10 cm when a video is playing on the smart µLED display without any lens.…”
