Among his latest inventions is a level detector designed to provide excellent linearity and high detection efficiency. This compact and cost-effective device is particularly suitable for use in semiconductor integrated circuits. The level detector utilizes a common emitter amplifier with two transistors connected in parallel, effectively eliminating odd order harmonic distortion components while allowing DC and even order harmonic components to be present at the collector. Additionally, it features a high impedance load composed of a transistor that is normally biased in its active region, enhancing detection efficiency.
Another notable invention is the electronically controlled variable semiconductor resistor. This device has a three-layer construction, either NPN-type or PNP-type, similar to that of a bipolar transistor. It utilizes the base and collector regions of the transistor as a variable resistor, with its resistance value controlled by varying the emitter current. The design allows for significant modulation of the conductivity in the base and collector regions, enabling the creation of a variable resistor whose resistance inversely correlates with the emitter current.
