Latest Patents
Tatsuya Sawa holds a patent for a "System and method for providing a sample and hold circuit for maintaining an output voltage of a constant current source circuit when a feedback loop is disconnected." This invention involves a constant current source circuit that includes a voltage regulator, two feedback loops, and a sample and hold circuit. The voltage regulator is designed to regulate an output voltage (VOUT) to a reference voltage (VREF) using a feedback voltage signal from the first feedback loop. The sample and hold circuit plays a crucial role by sampling and holding a second feedback voltage signal from the second feedback loop while the first feedback loop remains connected. When the first feedback loop is disconnected, the voltage regulator adjusts the output voltage to the second feedback reference voltage signal.
