  • Current-mode CMOS logarithmic function circuit
    Patent number: 8779833
    Abstract: The current-mode CMOS logarithmic function circuit provides an ultra-low power circuit that produces an output current proportional to the logarithm of the input current. An OTA (operational transconductance amplifier) constructed from CMOS transistors, in combination with two PMOS transistors configured in weak inversion mode for providing a reference voltage input and a voltage input from the input current to the OTA, provides the circuit with a high dynamic range, controllable amplitude, high accuracy, and insensitivity to temperature variation.
    Type: Grant
    Filed: March 12, 2012
    Date of Patent: July 15, 2014
    Assignee: King Fahd University of Petroleum and Minearals
    Inventors: Karama M. Al-Tamimi, Munir Ahmed Al-Absi
