Latest Patents

Oong is associated with 1 patent, titled “System and Method for Virtual Resistance.” The invention describes a control system designed to improve dynamic performance in constant-voltage (CV) mode while remaining invariant to the source type and operating point. It achieves this by using a voltage-controlled resistance as the control element in the system’s feedback loop, replacing a voltage-controlled current source, potentially with few or no additional circuit components. The system measures an input voltage from a device under test, determines a feedback control voltage based at least partly on that measurement, and applies the combined voltage to operate the device in CV mode.
