Abstract: A method and apparatus for a method of calibrating a transmit digital to analog converter full-scale current. The method comprises generating a tuned reference current and then calibrating the tuned reference current to a selected value in order to produce a predetermined current value. The calibration further comprises dividing a reference voltage input over a resistor string. A band gap current is then generated using the divided reference voltage input. A tuned current output is then produced from a current steering digital to analog converter with the tuned output current stored in a register. The reference current for the transmit DAC is then generated based on the stored tuned output current.

Abstract: Compensated current cell to scale switching glitches in digital to analog convertors. A compensated current cell is disclosed that includes first and second switching transistors configured to switch an input current between first and second outputs based on first and second input signals, respectively, a first compensation transistor connected to the first input signal to provide a first compensation current that is connected to the second output, and a second compensation transistor connected to the second input signal to provide a second compensation current that is connected to the first output, the first and second compensation transistors having source terminals that are connected together. In another aspect, switching glitches are scaled based on a size difference between the switching transistors and the compensation transistors.

Abstract: The present invention is directed to a cover for a container. The cover includes a moveable member and a motor having armature connected to the moveable member. A sensor generates a sensing signal when motion is detected. A controller is connected to the sensor and the motor. The controller receives the sensing signal from the sensor and activates the motor to move the moveable member from a closed position to an opened position. After a predetermined period of time, the controller deactivates the motor to move the moveable member from the opened position to the closed position.
