Title: The Innovations of William H. Gross
Introduction
William H. Gross is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of electrical engineering, particularly in the design of operational amplifiers. With a total of 2 patents to his name, Gross continues to push the boundaries of innovation in his field.
Latest Patents
One of Gross's latest patents is the "Low Voltage Op Amp Bias Optimizer." This operational power amplifier features a bootstrap power output stage designed to maximize dynamic range across a wide range of supply voltages. A control circuit, in the form of a switched current mirror, is integrated into the amplifier's biasing circuit. When the supply voltage exceeds a predetermined threshold, the amplifier bias is adjusted to provide half of this voltage at the output terminal. Conversely, for supply voltages below the threshold, the output voltage is kept less than half of the supply voltage.
Another significant patent is the "One and One Half Pole Audio Power Amplifier Frequency Compensation." This innovation involves an integrated circuit audio power amplifier that achieves a 6 dB per octave frequency-gain roll-off by converting a high-gain inverter into an integrator, which is then driven by a current source. A second cascaded stage operates at a lower gain, providing a matching high-frequency roll-off. The combination of these characteristics results in a 12 dB per octave roll-off at higher frequencies, while a flat negative feedback loop maintains a controlled constant low-frequency gain.
