    Abstract: The present disclosure provides methods and apparatuses for performing light detection and ranging (LiDAR). In some embodiments, a device includes a light transmitter configured to radiate, to an object, light comprising a transmission signal, a light receiver configured to receive light reflected from the object, an integrator configured to obtain, by integrating a reception signal obtained from the received light, an analog signal corresponding to a convolution result between the reception signal and the transmission signal, and a processor configured to measure, by a time-of-flight (ToF) method, a distance from the device to the object, based on the analog signal.

    Abstract: A current stimulator includes a first current generation circuit configured to generate a first current, injectable into a cranial nerve cell, through a current mirroring based on a plurality of transistor pairs; and a second current generation circuit, driven by a clock, configured to generate a second current smaller than the first current by controlling a charge rate based on a voltage difference between terminals of a capacitor. A first output impedance of the first current generation circuit and a second output impedance of the second current generation circuit have a magnitude greater than or equal to a predetermined ratio to a load impedance corresponding to the cranial nerve cell.
