Abstract: The present invention relates to a method of time-domain magnetic resonance imaging and device thereof. The method includes transiently exciting a sample; receiving a signal emitted form the sample; and processing the received signal without Fourier transformation to acquire an image. The device includes an excitation device, a detecting coil and an operating circuit to process a received emitting signal and generating an image, wherein the received emitting signal is a time-domain signal free from Fourier transformation. The time of generating an image can be reduced dramatically by the present invention.

Abstract: Disclosed is a designed and implemented 12-bit 70 Msps pipeline analog-to-digital converter. Two adjacent blocks operate at opposite clock phases to reduce the chip size and power consumption. Since the opposite clock phases are designed to be provided by external devices, the timing between these two clock phases must be accurate. Note that the architecture of pipeline ADC consists of four stages, divided into two groups, wherein two adjacent stages in each group share one 3-bit flash ADC, hence only two 3-bit flash ADCs are required in this scheme. Therefore, there are 6-bit signal produced from each 3-bit flash ADC within one clock phase which consists of two opposite clock phases. And within the same period, the total output of the pipeline analog-to-digital converter would be 12-bit. From the simulation results, when the sampling rate is 70 Msps, this converter consumes 155 mW (TBV) at a ±1.8 V supply.
