摘要： A multi-phase clock generator including a first delay locked loop, a reference signal generator and a second delay locked loop is provided. The first delay locked loop generates 2N phase clock signals according to an input clock signal, so as to equally divide a clock period of the input clock signal into 2N predetermined phases, where N is a positive integer. The reference signal generator selects two phase clock signals according to a digital signal, and adjusts an output ratio of the two phase clock signals in 2M clock periods to serve as a reference clock signal. The second delay locked loop delays a first phase clock signal according to a phase difference between the reference clock signal and an output clock signal. In this way, each predetermined phase is further equally divided into 2M sub-phases, so that the multi-phase clock generator has 2(N+M) phase selections.

摘要： Example computer-implemented methods, computer-readable media, and computer systems are described for providing communication protocol architecture or framework for magnetic induction (MI)-based communications in wireless underground sensor networks (WUSNs), for example, in underground oil reservoirs. In some aspects, environment information of an underground region that affects the transmission qualities of MI communications is evaluated. A protocol stack is identified. The protocol stack includes a number of layers for MI communications among a number of sensors in a WUSN in the underground region. A cross-layer framework and the distributed protocol are built to jointly optimize communication functionalities of the plurality of layers based on the evaluation.

摘要： A spread-spectrum generator is provided. The spread-spectrum generator includes a delay module and a control module. The delay module is controlled by a first control signal to delay an input signal by a delay time, and thereby generate a delay signal. The control module is coupled to the delay module for detecting a first edge of the delay signal, and thereby generating the first control signal. Accordingly, the spread-spectrum generator can spread the frequency of the input signal by delaying the input signal by various delay time, and the spread-spectrum generator can also reduce electromagnetic interference (EMI).

摘要： The clock signal detection circuit includes a lock detection circuit, a duty cycle detection circuit, a first logic circuit, and a counter. The lock detection circuit detects whether an input clock signal and a feedback clock signal of a delay locked loop are in phase. The duty cycle detection circuit detects whether the duty cycle of the input clock signal is within a percentage range. The first logic circuit, electrically connected to the lock detection circuit and the duty cycle detection circuit, outputs a detecting result signal which is at first logic level when the input clock signal are in phase with the feedback clock signal, and the duty cycle of the input clock signal is within a percentage range. The counter outputs a lock detection signal which is at the first logic level when the detecting result signal has maintained at the first logic level for a first constant period of time.
