“…[23]- [27]) have focused mainly on the development of an integrated receiver for a pulsed TOF laser radar without complete characterization of the device at the system level nor concurrent time-to-digital converter development. In [25]- [26], the timing accuracy is less than ±75 mm within a dynamic range of approximately <1:10,000, whereas millimetre-level accuracy was achieved over a wider dynamic range in the present study, however at a cost of somewhat higher noise. A complete receiver TDC chip set was developed in [14] but the dynamic range and accuracy are worse with a factor of ~10 compared to the present design.…”

An integrated receiver-TDC (time-to-digital converter) chip set is developed for pulsed time-of-flight (TOF) laser rangefinding. The receiver detects the current pulse from the optical detector and produces a timing mark for the TDC. The receiver uses time mode walk error compensation scheme achieving <+/-2.5 mm residual timing walk error within a dynamic range of ~1:40,000. The multi-channel TDC measures the time position, width and rise time of the echo pulses simultaneously with ~ 10 picosecond (ps) precision. Both chips are manufactured in 0.35-µm complementary metal-oxide semiconductor (CMOS) technology. The functionality of the chip set was demonstrated in a laser radar platform using 12 W and 3-ns optical pulses produced by a laser diode. A measurement accuracy of ~+/-3 mm was achieved with non-cooperative targets at a distance range of a few tens of metres within an amplitude range of received echoes of 1:40,000.

“…The operation of the proposed 16-to-1 TICA receiver was only verified in an electrical response test with an electrical current pulse, and the prototype STUD-based LADAR sensor as a front-end circuit was verified for the largest area photodetector with CPDT of 32 pF through the PPC method. Table 1 shows the performance summary of the prototype chip with a comparison to other works [7,11,[22][23][24][25]. Compared to other works, the prototype of the proposed 16-to-1 TICA covers the largest area photodetector of 32 pF for high spatial resolution and worked well as the general TIA.…”

This paper presents a static unitary detector (STUD)-based laser detection and ranging (LADAR) sensor with a 16-to-1 transimpedance-combining amplifier for high spatial resolution three-dimensional (3-D) applications. In order to readout the large size of a photodetector for better results of 3-D information without any reduction of the bandwidth, the partitioning photosensitive cell method is embedded in a 16-to-1 transimpedance-combining amplifier. The effective number of partitioning photosensitive cells and signal-combining stages are selected based on the analysis of the partitioning photosensitive cell method for the optimum performance of a transimpedance-combining amplifier. A prototype chip is fabricated in a 0.18-μm CMOS technology. The input referred noise is 41.9 pA/√Hz with a bandwidth of 230 MHz and a transimpedance gain of 70.4 dB·Ω. The total power consumption of the prototype chip is approximately 86 mW from a 1.8-V supply, and the TICA consumes approximately 15.4 mW of it.

“…As a TIA, the most popular configuration has been a voltage-mode inverter with a feedback resistor. But, this inverter TIA has an inherent design trade-off between transimpedance gain and bandwidth, which may lead to considerable noise increase and sensitivity degradation [22]. Therefore, we have employed the VCF-TIA in this work, hence clearly detecting the targets of 5% reflection rate within the range of 0.5-25 m.…”

This chapter presents several CMOS integrated circuits (ICs) realized for various optical applications such as high-definition multimedia interface (HDMI), light detection and ranging (LiDAR), and Gigabit Ethernet (GbE). First, 4-channel 10-Gb/s per channel optical transmitter and receiver array chipset implemented in a 0.13-μm CMOS process are introduced to realize a 10-m active optical cable for HDMI 2.1 specifications. Second, a 16-channel optical receiver array chip is realized in a 0.18-μm CMOS technology for LiDAR applications. Third, a 40-GHz voltagemode mirrored-cascode transimpedance amplifier (MC-TIA) is implemented in a 65-nm CMOS for a feasible 100-GbE application. Even with advanced nano-CMOS technologies, we have suggested novel circuit techniques for optimum performance, such as input data detection (IDD) for low power, feedforward and asymmetric preemphasis for high speed, double-gain feedforward for high gain, selectable equalizer (SEQ) for specific bandwidth, mirrored-cascode for fully differential topology, etc. We believe that these novel circuit techniques help to achieve low-cost, low-power solutions for various optical applications.
