Latest Patents
One of Ueda's latest inventions is a temperature detection circuit. This circuit includes a bandgap reference voltage generation circuit, a detection output circuit, and an output conversion circuit. The bandgap reference voltage generation circuit generates a first reference voltage and causes a bias current to flow through a current path to produce a thermal voltage. The current path features a first resistor. The detection output circuit, which has a second resistor, causes a mirror current of the bias current to flow through the second resistor. The output conversion circuit utilizes a second reference voltage to convert the voltage drop across the second resistor into a predetermined output form for temperature detection. Notably, the first and second resistors are substantially identical in temperature dependence, and the second reference voltage is generated from the first reference voltage.
Another significant invention by Ueda is a noise-free transceiver circuit. This circuit comprises a communication line, a power source line, and a ground line. It features an output transistor with output terminals connected between the communication line and the ground line for outputting a communication signal. A first circuit applies a trapezoidal signal to the input terminal of the output transistor to turn it on in synchronism with a transmission signal. A second circuit turns off the output transistor when the level of the transmission signal is high. This design effectively shuts out noise from the power line, ensuring a clean output signal.
