Abstract
A method of controlling an analog signal in an integrated circuit includes generating a first control signal having a first predetermined duration within the integrated circuit. The first control signal is configured to cause the analog signal to have a first signal level. The first signal level is compared to a level of a target signal. A second control signal is generated within the integrated circuit based on a result of the comparison. The second control signal is configured to cause the analog signal to have a second signal level. The second control signal has a second predetermined duration that is different than the first predetermined duration.
Claims17
A method of controlling an analog signal in an integrated circuit, the method comprising:
- generating a first control signal within the integrated circuit, the first control signal having a first predetermined duration and configured to cause the analog signal to have a first signal level;
- comparing the first signal level to a level of a target signal;
- and
- generating a second control signal within the integrated circuit based on a result of the comparison, the second control signal configured to cause the analog signal to have a second signal level, the second control signal having a second predetermined duration that is different than the first predetermined duration, wherein the first and second control signals are generated based on a binary search algorithm.
An integrated circuit, comprising:
- an output driver circuit configured to output a first analog signal based on a first control signal having a first predetermined duration;
- and
- a control circuit configured to compare the first analog signal to a reference analog signal, and generate a second control signal based on a result of the comparison to modify the first analog signal, the second control signal having a second predetermined duration that is different than the first predetermined duration, wherein the control circuit is configured to generate control signals based on a binary search algorithm.
