  • Controllable constant current supply integrated circuits for driving dense arrays
    Patent number: 10178772
    Abstract: A controllable current driver integrated circuit is provided. The controllable current driver includes a multitude of different current value output transistors digitally controlled and combined to provide a controllable current output. The different current value transistors are each provided as single lithographic devices on a same substrate in proximity to each other having weighted drain and source areas corresponding to the different current values. The weighted drivers reduce the implementation area required on the semiconductor die for decoding and driving the output transistors substantially increasing the density of current drivers which can be integrated in one semiconductor die.
    Type: Grant
