An optical communication receiver system is presented in this research using 65nm CMOS, which consists of three lowpower active differential stages as Limiting Amplifier (LA) following an ultra-low-power RGC-Based Transimpedance Amplifier (RB-TIA). The presented active circuit of the RB-TIA is followed by a gain stage that extends the-3dB frequency of the circuit by creating a resonance for the load capacitance. Thus, needless of consuming extra power, a wide-bandwidth circuit has been designed. In addition, employing active-inductor loads within the LA stages enables obtaining a 5Gbps receiver system. The RB-TIA consumes 573µW and provides 3.52GHz frequency, while the complete optical receiver consumes only 4.76mW power to provide-3dB frequency of 3.5GHz and high gain of 80dB (10'000). The circuits have been mathematically presented and discussed, and simulations have justified the presented circuit design.

Mirrored Current-Conveyor Transimpedance Amplifier for Home Monitoring LiDAR Sensors

This article presents a current mode transimpedance amplifier (TIA) implemented in a standard 65-nm CMOS technology for the applications of elder-care home monitoring LiDAR sensors. Particularly, a novel mirrored current-conveyor (MCC) input configuration is proposed to lower the input impedance, thus achieving a wide bandwidth. This MCC-TIA can alleviate severe pulse spreading issue for near-range detection, enabling effective narrow-pulse recovery. Also, a feedforward control-voltage generator is newly suggested to realize an automatic gain-control within a single pulse-width duration. Measured results demonstrate the variable transimpedance gain of 59∼77 dB to accommodate the incoming input currents of 18 μA pp ∼ 2.24 mA pp that corresponds to the feasible detection range of 0.5∼5.3 meters in an elder's home. The bandwidth of 83 MHz∼2.6 GHz is measured with the minimum noise current spectral density of 16.8 pA/sqrt(Hz). The chip dissipates 40 mW in total, and occupies the area of 1.0 mm 2 , including I/O pads.

A fully integrated visible light communication (VLC) receiver is presented in this paper. The proposed VLC receiver chip is designed for free-space communication. Utilizing a laser diode as light source, the measured −3 dB bandwidth of receiver is 420 MHz over 0.5 m distance without lens. The integrated receiver is manufactured in an UMC 0.18 µm CMOS process, and the chip area is 889 × 570 µm 2. This receiver chip can be used in VLC systems with the following advantages: suitable for VLC free-space channel, low requirements for focusing and alignment, low cost, low power-consumption, compatible with standard CMOS technology, and high integration-density.
