Abhaya Kumar is a prominent inventor based in Bengaluru, India. He has made significant contributions to the field of light radar technology, holding a total of 9 patents. His work focuses on enhancing the capabilities of LIDAR systems, which are crucial for various applications, including autonomous vehicles and environmental monitoring.

Latest Patents

One of his latest patents is a "Light radar signal processing apparatus, systems and methods." This invention involves storing samples of a LIDAR return signal in an analog circular buffer after transmitting a LIDAR pulse. The sampling continues for a fixed period or number of samples during a post-trigger sampling period, triggered by a signal from a trigger circuit. This circuit indicates the receipt of a return pulse associated with a target object based on specific return signal characteristics. After the post-trigger sampling period, the stored analog samples are read out and converted to digital values. These digital values can be analyzed to confirm the validity of the returned LIDAR pulse, determine its time of arrival, and calculate the distance to the target object. Some versions of this invention include multiple circular buffers and capture clocks, allowing for the capture of samples from multiple return pulses.

Another notable patent is for "Common mode stabilization in a fully differential amplifier." This invention features a fully differential amplifier circuit that includes a stabilization block to measure the common mode component at the output of an input stage. It injects a current proportionate to this component into each of the output paths to stabilize the feedback loop formed by the input stage, output stage, and common mode feedback block. The stabilization block contains a buffer to receive the measured common mode component, ensuring that the differential loop remains unaffected by the additional current injection, thus avoiding distortions in the output signal.
