He has made significant contributions to the field of electronics, particularly in the development of clock pulse generators and digital-to-analog conversion circuitry. With a total of 2 patents, Ohnishi continues to push the boundaries of innovation in his field.

Latest Patents

One of Ohnishi's latest patents is a clock pulse generator. This device includes an input terminal, an input bias setting circuit, first and second pulse shaping circuits, and a pulse combining circuit. The input terminal receives a sinusoidal signal, while the input bias setting circuit generates an additional sinusoidal signal with a predetermined bias voltage. The first and second shaping circuits respond to this signal to produce pulse signals, which are then synchronized to generate an output clock pulse.

Another significant patent is the digital-to-analog conversion circuitry that incorporates a simplified testing circuit. This circuitry includes a DA converter that initially applies test data of "0". The converter feeds an analog voltage corresponding to this data to a voltage holding circuit. As the test data is incremented to "1", the DA converter generates a corresponding analog voltage. A comparator then compares these voltages, allowing for easy and rapid testing of the DA converter's functionality.
