    摘要: An absolute time delay generating device includes a PVT (process-voltage-temperature) detection device and a delay-timing generator. The PVT detection device includes at least a delay module and a signal phase/frequency control module. The delay module includes a control unit and a reference unit. The control unit differs from the reference unit in sensitivity of delay property to PVT. The delay module compares phase or frequency differences generated when origin signals pass through the control unit and reference unit respectively, and produce delay parameters of the delay module. The signal phase/frequency control module receives and compares the delay parameters to determine an ambient PVT condition for the absolute time delay generating device, so as to control and correct the delay-timing generator and thereby generate accurate absolute time delay. Under various PVT influences, the absolute time delay generating device is capable of generating accurate, absolute time signals.

    摘要: A communication device uses a local clock generator to regenerate the carrier frequency of the reference signal from a remote communication. In particular, a closed loop is used to self-calibrate the local pulse till the frequency is fixed to be within a fixed frequency margin. Once the local pulse is obtained, the demodulator will use the local pulse to demodulate the reference signal to generate the data signal.

    摘要: This invention discloses a crystal-less communication device and self-calibrated embedded virtual crystal clock generation method. In communication systems, the invention proposes a crystal-less scheme in the device for wireless or wired-line communications. The operation concepts are that the transmitter Device-1 provides Device-2 a reference signal, and Device-2 takes this signal to generate a local signal with the similar frequency that has limited frequency error compared with the one from Device-1. This invention is done via the circuit-design methodology, so it can be implemented from any kinds of circuit implementation processes, especially the CMOS process. As a result, the hardware can be designed in the way of highly integration and extremely low cost. Also, this can largely change and improve existing communications design architecture, hardware cost, and hardware area.

    摘要: A delay cell includes a first inverted transistor pair, a second inverted transistor pair and a plurality of delay units. The first inverted transistor pair is used to receive an input signal. The second inverted transistor pair is electrically cross-coupled to the first inverted transistor pair and cross-controlled by the first inverted transistor pair. The delay units are cascaded between the first inverted transistor pair and between the second inverted transistor pair, thereby providing a plurality of signal propagation delays sequentially, wherein the input signal is delayed for a pre-determined time by the first inverted transistor pair, the second inverted transistor pair and the delay units which are operated sequentially, thereby creating an output signal corresponding to the pre-determined time. A digitally controlled oscillator including the aforementioned delay cells is provided.

    摘要: In a cyclic code decoding method, a decoder analyzes a received codeword to identify unreliable symbols in the codeword, and sets candidate syndrome patterns accordingly. Then, a syndrome calculator calculates evaluated syndrome values associated with one of the candidate syndrome patterns, and an error location polynomial (ELP) generator generates an ELP according to the syndrome values. An error correction device corrects the errors in the codeword according to the ELP when a degree of the ELP is not more than a threshold value, and the syndrome calculator adjusts the syndrome values and the ELP generator generates another ELP according to the adjusted syndrome values when otherwise.

    摘要: An operating method and a circuit for low density parity check (LDPC) decoders, in which original bit nodes are incorporated into check nodes for simultaneous operation. The bit node messages are generated according to the difference between the newly generated check messages and the previous check node messages. The bit node messages can be updated immediately, and the decoder throughput can be improved. The required memory of LDPC decoders can be effectively reduced, and the decoding speed can also be enhanced.
