Title: Gopinath Ranganathan: Innovator in Electro-Optic Technologies
Introduction
Gopinath Ranganathan is a notable inventor based in Singapore, SG. He has made significant contributions to the field of electro-optic technologies, holding 2 patents that showcase his innovative approach to solving complex problems in device testing.
Latest Patents
Ranganathan's latest patents include groundbreaking work in the analysis of electro-optic waveforms. His first patent describes an optic probe used to measure signals from a device under test. The optic probe is strategically positioned at a target probe location within a cell of the device, which includes a target net to be measured and several non-target nets. A test pattern is applied to the cell, and a laser probe (LP) waveform is obtained in response. The target net waveform is extracted from the LP waveform through a detailed process involving combinational logic analysis (CLA) to model cross-talk from selected non-target nets. This innovative method allows for precise measurement and analysis of the target net's performance.
His second patent focuses on probe placement for a laser probing system. This control system utilizes a receiver circuit that captures reflected light from the optic probe, generating an LP waveform in response to a trigger signal. A CLA processor simulates the optical response at a target location on the device's surface to a test pattern. The test controller then updates the position signal to move the optic probe closer to the target location based on the fit between the LP waveform and the CLA waveform.
