Abstract: A system and method for operating a high dynamic range analog front-end receiver for long range LIDAR with a transimpedance amplifier (TIA) include a clipping circuit to prevent saturation of the TIA. The output of the clipping circuit is connected via a diode or transistor to the input of the TIA and regulated such that the input voltage of the TIA remains close to or is only slightly above the saturation threshold voltage of the TIA. The regulation of the input voltage of the TIA can be improved by connecting a limiting resistor in series with the diode or transistor. A second clipping circuit capable of dissipating higher input currents and thus higher voltages may be connected in parallel with the first clipping circuit. A resistive element may be placed between the first and second clipping circuits to further limit the input current to the TIA.

Abstract: Apparatus and methods for assisting a voltage regulator. In an example, a voltage regulator can include an error amplifier configured to compare a reference voltage with a representation of an output voltage of the voltage regulator, an output transistor coupled to a supply voltage and configured to receive an output of the error amplifier and to provide the output voltage, and an auxiliary-current circuit including a helper transistor having a terminal coupled to the output voltage, the helper transistor configured to turn on when the output voltage drops due to current demand from the load and to provide charge current to the load in addition to current provided by the output transistor.

Abstract: Aspects of this disclosure relate to a receiver for a light detection and ranging system. The receiver includes a transimpedance amplifier that is operable in a linear mode for a range of power of light received by the receiver. The receiver can provide information about amplitude of the light outside of the range of power of the light for which the transimpedance amplifier operates in the linear mode. This information can be useful, for example, in identifying an object from which light received by the receiver was reflected.

Abstract: Embodiments of the present disclosure provide an optical range finder that includes a transimpedance amplifier (TIA) and a photodiode emulation circuitry for testing the TIA. The photodiode emulation circuitry may be coupled to an input port of the TIA and configured to receive one or more parameters specifying one or more characteristics of a test current signal to be provided to the TIA. The photodiode emulation circuitry may further be configured to provide the test current signal in accordance with the one or more parameters to the input port of the TIA while the photodiode is also coupled to the input port of the TIA.
