| Abstract: | An integrated receiver channel for a pulsed time-of-flight(TOF) laser rangefinder has been designed.RGC-TIA,MOS_L,and Modified Cherry-Hooper amplifier are used to make the receive channel.The simulation result shows the bandwidth of the trans-impedance amplifier is 90 MHz with 5 pF load capacitor and DC gain is up to 134 dB·Ω.Taping out in standard 0.5 μm CMOS Process Line,the chip is packaged and measure.It shows that root mean square of output voltage is 2.4 mV and the delay time of pulse responsibility is 6 ns. |
