Method and system for a control scheme on power and common-mode voltage reduction for a transmitter
View Patent ↗Provided is a method and system for controlling current characteristics in a transceiver having a transmitter. The method includes identifying a phase control signal from an adjacent current cell preceding the particular current cell in time and logically ORing the phase control signal from the preceding cell with a phase control signal from the particular current cell.
1. A current control logic device, comprising;
predictive logic configured to advance a leading edge of an input signal; and
a logic device having one input coupled to an output of the predictive logic and another input configured to receive the input signal.
2. The current control logic device of claim 1 , wherein the input signal is a wake-up signal; and
wherein an output of the logic device is configured to be provided as an input to a current source.
3. A method for activating an individual current cell within a plurality of interconnected current cells, the method comprising:
providing a respective wake-up signal to each of the cells; and
logically combining particular ones of the respective control signals with a respective control signal output from an adjacent cell.
4. The method of claim 3 , wherein the logically combining includes an ORing operation.
5. The method of claim 3 , wherein the logically combining includes ORing the particular one of the respective control signals with a respective control signal from a previous cell.
6. An apparatus for activating an individual current cell within a plurality of interconnected current cells, the apparatus comprising:
means for providing a respective wake-up signal to each of the cells; and
means for logically combining particular ones of the respective control signals with a respective control signal from an adjacent cell.
7. The apparatus of claim 6 , wherein the logically combining includes an ORing operation.
8. The apparatus of claim 6 , wherein the logically combining includes ORing the particular one of the respective control signals with a respective control signal from a previous cell.
