He holds three patents that showcase his innovative approach to voltage detection and amplifier systems. His work has significantly impacted the design and functionality of electronic devices.

Latest Patents

One of Niki's latest patents is a voltage detection circuit that utilizes a threshold as a reference voltage. This circuit is designed to compare an input voltage against a reference voltage derived from the threshold voltage of a semiconductor active device. To ensure that the detection circuit remains independent of ambient temperature changes, it is constructed as an integrated circuit. This design includes devices that produce a temperature-dependent voltage that cancels out the temperature-sensitive voltage component of the reference voltage, allowing for a temperature-independent voltage comparison.

Another notable patent is an amplifier system that is switchable between two amplifying operations. This amplifier includes first and second amplifying circuits, each with a non-inverting input, an inverting input, and an output. The system is designed to receive two input signals and can selectively apply these signals to either amplifying circuit. A controlling circuit manages the operation of the amplifier, allowing it to function as both a dual-channel amplifier and a BTL amplifier.
