Abstract: A circuit (34) for data recovery in a wireless powered communication device (10) obviates the need for the costly high power consumption filters of prior art devices by deriving a clock signal from the power coil (18), and then sampling the data coil (20) signal with the derived sampling clock. The step of deriving a clock signal from the power signal causes the component of the power signal present on the data signal to be aliased to DC which is then easily rejected with a low order high pass or bandpass filter (38). Furthermore, the data signal may be amplified to a desired level suitable for amplitude discrimination by a simple comparator circuit (40) with hysteresis. Demodulation of the data signal is easily accomplished in the digital domain using a digital demodulator (32).

Abstract: An electronically calibrated sensor (100) includes a sensing element (102) with an output coupled to a signal conditioning circuit (104). The signal conditioning circuit (104) is adapted to be highly computationally efficient and operable for compensating for temperature and part-to-part variation on the sensing element output for providing a useable sensor output signal. The signal conditioning circuit (104) includes an analog-to-digital/digital-to-analog (ADC/DAC) conversion device (112). The ADC/DAC (112) is operable to perform both analog input signal analog-to-digital conversion and digital output signal digital-to-analog conversion. The ADC/DAC (112) is further adapted to provide analog control signals to input signal conditioning circuits (104, 106).
