An analog-storage based analog-to-digital converter (ADC) was designed for the applications of pulsed light detection and ranging (LiDAR), where a high speed sequence control logic circuit and an analog-storage array were designed, combined with a low speed pipelined ADC and an accompanied phase-locked-loop (PLL) circuit. The simulation results showed that the proposed analog-storage based ADC could achieve an equivalent performance of 16 GHz ADC by a low speed 25 MHz ADC in the actual applications of LiDAR.
