    摘要: A digital delay line includes a plurality of hysteresis-based delay cells electrically connected in series. These hystersis delay units in the hysteresis-based delay cells may be similar or different. All of the hysteresis delay units respectively have an inverter mode and a hesteresis mode. The delay and resolution of the hysteresis delay unit may be derived from the time difference in the inverter mode and hysteresis mode. Such a digital delay line applied to a digital phase locked loop may reduce consumption of area and power.

    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.
