摘要： An AD converter includes a VT converter circuit part which inputs an analog input voltage and a sampling clock, converts the analog input voltage to a corresponding delay time, and outputs time domain data. A ring oscillator circuit part of N stages inputs the time domain data, and an error propagation circuit part takes out delay information containing a quantization error from phase information of the ring oscillator circuit part of the previous stage, and propagate the delay information to the ring oscillator circuit part of a subsequent stage. A counter circuit part measures a number of waves of an output oscillation waveform of the ring oscillator circuit part of each stage, and an output signal generator part generates an output signal from an output counted value of each counter circuit part. A reset part resets each error propagation circuit part and each counter circuit part with a sampling clock.

摘要： A sensor network system including node devices connected in a network via predetermined propagation paths collects data measured at each node device to be aggregated into one base station via a time-synchronized sensor network system. The base station calculates a position of the signal source based on the angle estimation value of the signal from each node device and position information thereof, designates a node device located nearest to the signal source as a cluster head node device, and transmits information of the position of the signal source and the designated cluster head node device to each node device, to cluster each node device located within the number of hops from the cluster head node device as a node device belonging to each cluster. Each node device performs an emphasizing process on the received signal from the signal source, and transmits an emphasized signal to the base station.
