Latest Patents

Jihee Lee holds two patents, with his latest focusing on methods and circuitry for built-in self-testing of circuitry and/or transducers in ultrasound devices. The technology described in this patent relates to built-in self-testing (BIST) of circuitry, such as a pulser or receive circuitry, and/or transducers in ultrasound devices. A BIST circuit may include a transconductance amplifier coupled between a pulser and receive circuitry, a capacitor network coupled between a pulser and receive circuitry, and/or a current source couplable to the input terminal of receive circuitry to which a transducer is also couplable. The collapse voltages of transducers may be characterized using BIST circuitry, and a bias voltage may be applied to the membranes of the transducers based at least in part on their collapse voltages. Additionally, the capacitances of transducers may also be measured using BIST circuitry, and a notification may be generated based on the sets of measurements.
