In this work, 4-to-1 combined pixel array for front-end readout integrated circuit of laser radar is developed in SK Hynix 0.18 μm CMOS technology. As a mixed circuit type, 4-to-1 combined unit pixel consists of 4-to-1 transimpedance combining amplifier, comparator and time-to-voltage converter with control logic blocks. Here, 8 × 8 combined pixel array is implemented and tested for 3-demensional (3-D) range detection. The power for the array is supplied from 1.8 V supply and the bandwidth is under 1 GHz.
