In this SPICE simulation a photodiode OPT101 with on-chip transimpedance amplifier with single power supply, when a light is detected produces an analog output. A TLC339, used as comparator, converts the analog output to TTL output. The photodiode uses a resistor feedback to increase the detector’s band and a capacitor for frequency compensation stability.
