Abstract: A medical sensor includes an application-specific integrated circuit (ASIC), medical hardware, and a communication module. The ASIC is communicatively coupled to the medical hardware and communication module. The ASIC is configured to receive measurement signals from the medical hardware and provide the measurement signals to the communication module. The communication module is configured to process the measurement signal into measurement results and transmit the measurement results to a remove device. The communication module includes an application layer for processing the measurement signals and a link layer for transmitting the measurement results. The ASIC is configured to detect that a voltage supplied to the ASIC is below a threshold level and determine an amount of time that the voltage has been below the threshold level. The ASIC is further configured to respond to the voltage supplied to the ASIC being below a threshold level based on the determined amount of time.

Abstract: Power converters that produce less noise are disclosed. For example, in an embodiment, power converter can include a first inductor magnetically coupled to a second inductor, wherein a first end of the second inductor is electrically open and a second end of the second inductor is electrically coupled to ground via a second capacitor, a transistor electrically connected to the first inductor, and control circuitry to control switching of the transistor, wherein when the transistor is repeatedly switched on and off by the control circuitry, a current loop is formed through the transistor, the second capacitor, the first inductor and the second inductor, the current loop causing a reduced amount of switching noise to be generated by the power converter.
