摘要： An analogue to digital converter uses charge sampling in combination with a successive approximation conversion technique in order to combine anti-alias filtering and quadrature downconversion functions into the data converter. The conversion method is an energy-efficient realization for wide-band radio systems with moderate resolution specifications such as 4G or ultra-wideband radio (UWB). The converter uses two capacitor matrices, one to perform charge sampling, and one to be used simultaneously in the successive approximation technique, so that full use of an input signal is made and efficiency is maximised.

摘要： An energy-efficient acceleration measurement system is presented. The system includes an accelerometer, responsive to acceleration of the system, for providing an accelerometer output signal having a magnitude indicative of at least one component of the acceleration. A motion detector is responsive to the accelerometer output signal, and provides a processor interrupt signal, but only if the magnitude of acceleration reaches a threshold. The processor, responsive to the processor interrupt signal, measures the acceleration with higher accuracy than the motion detector is capable of, but in a way that consumes more power than was needed by the motion detector.
