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.

摘要： An embodiment of an amplifier includes an amplifier output node operable to provide an output signal, and an output stage. The output stage includes a drive buffer having an input node and an output node, a drive transistor, and a compensation capacitor. The drive transistor has a control node coupled to the output node of the drive buffer, a first drive node, and a second drive node coupled to the amplifier output node. And the compensation capacitor has a first node isolated from the control node of the drive transistor by the drive buffer, and has a second node coupled to the amplifier output node. By buffering the control node of the drive transistor, one may reduce the level of nonlinear current referred back to the amplifier input as a nonlinear offset voltage, and thus may reduce the level of nonlinear distortion that his nonlinear offset voltage generates at the amplifier output.
