Latest Patents

One of his latest patents is a temperature sensing circuit. This circuit includes a bandgap voltage generation circuit, a current mirror branch, a variable resistor, a comparator circuit, a control circuit, and a temperature determining circuit. The bandgap voltage generation circuit generates a bandgap voltage, while the current mirror branch generates a mirrored current from this voltage. The variable resistor is connected to the current mirror branch to produce a variable voltage. The comparator circuit then compares the bandgap voltage with the variable voltage to generate a comparison result. The control circuit uses this result to adjust the resistance of the variable resistor, ultimately outputting a signal value that equalizes the variable voltage with the bandgap voltage. The temperature determining circuit then generates a temperature value based on this signal.

Another significant patent by Tu is an amplifying circuit. This circuit comprises a first gain circuit, a second gain circuit, a Miller capacitor, a positive feedback circuit, and a feedforward gain circuit. The second gain circuit receives a first gain signal from the first gain circuit and produces a second gain signal. The Miller capacitor, positive feedback circuit, and feedforward gain circuit are interconnected between the input and output terminals of the second gain circuit. The positive feedback circuit feeds back the output signal to the input terminal, while the feedforward gain circuit amplifies the first gain signal to produce a third gain signal at the output terminal.
