摘要： Provided herein are methods and systems that provide automatic compensation for frequency attenuation of a video signal transmitted over a cable. In accordance with an embodiment, a system includes an equalizer and a compensation controller. The equalizer receives a video signal that was transmitted over a cable, provides compensation for frequency attenuation that occurred during the transmission over the cable, and outputs a compensated video signal. The compensation controller automatically adjusts the compensation provided by the equalizer based on comparisons of one or more portions of the compensated video signal to one or more reference voltage levels. The compensating is selectively locked and reset in response to specific conditions being detected, e.g., a locking condition and a reset condition.

摘要： A system and method that compensates for the effects of ambient light in a time of flight (TOF) sensor front end is provided. Moreover, a direct current (DC) correction loop is utilized at the front end, which removes a DC component from a current generated by the TOF sensor and accordingly prevents saturating the front end. The DC correction loop attenuates the DC component without adding significant thermal noise at a modulation frequency and provides a corrected signal to the front end circuitry. The corrected signal is processed and utilized to detect a position of an object within the optical field of the sensor.

摘要： A system and method for automatically calibrating a Time-of-Flight (TOF) transceiver system for proximity/motion detection, is provided. Moreover, the system comprises a component that senses a signal (e.g., current or voltage) at an light emitting diode (LED), an attenuator, a signal injector at a sensor and a switching circuit that toggles between a normal mode (e.g., when signal from the sensor is input to the sensor front end) and a calibration mode (e.g., when signal from the attenuator is input to the sensor front end). During the calibration mode, the sensor front end identifies the phase delay error within the signal path, including board and/or package parasitic, and accounts for the phase delay error during proximity/motion detection in the normal mode.
