  • System and method for acoustic transducer supply
    Patent number: 10008990
    Abstract: According to an embodiment, a method of operating an acoustic device includes buffering, by a buffer circuit, a first electrical signal from an acoustic transducer to produce a second electrical signal, receiving a feedback signal at a supply circuit, and comparing the feedback signal to a first threshold. The feedback signal is based on the first electrical signal. The method further includes, based on comparing the feedback signal to the first threshold, switching between a first mode and a second mode, supplying a first supply voltage to the buffer circuit during the first mode, and supplying a second supply voltage to the buffer circuit during the second mode. The first supply voltage is different from the second supply voltage.

  • Bandwidth extension of oversampled analog-to-digital converters by means of gain boosting
    Patent number: 9577663
    Abstract: A digitized system operates to receive one or more analog signals from a sensor or other component and convert the analog signals to one or more digital signals. An analog-to-digital converter comprises a loop filter, a quantizer and one or more feedback digital-to-analog converters. A gain component provides coefficients along different points of a signal processing path to extend a bandwidth of the analog-to-digital converter. The gain component can modify a signal transfer function of the analog-to-digital converter while preserving a noise transfer function in order to process a signal in a higher frequency band in an extended mode of operation than other signals being processed in a normal operating mode.
