  • Circuit failure detection for diode arrays
    Patent number: 11927644
    Abstract: An apparatus and method for circuit failure detection for a diode array. The apparatus includes a diode array, a diode array test circuit electrically coupled to the diode array and operable to perform circuit failure detection during a test mode when a test input voltage is applied, the diode array test circuit includes an input resistor, an input voltage node, a buffered amplifier circuit, and a plurality of amplifier circuit switches. The apparatus further includes a current detector electrically coupled to the output of the buffered amplifier circuit and operable to determine, during the test mode, a current measurement of the pulse laser diode array.
    Type: Grant
