Title: Pll circuit
Inventor: ICHIMARU KOZO
IPC: H03L7/089
Filed: 2001-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a technique for a PLL circuit adopting the fractional frequency division system that can prevent the output signal in a locked state from including spurious components. SOLUTION: A frequency synthesizer 1 of this invention includes a charge pump circuit 35 having a period where sink and source currents differ from each other so as to differentiate a conduction start time of the source side upper operating transistors(TRs) from that of sink side lower operating TRs. Since the output signal from the charge pump circuit 35 includes no error component produced in that of a conventional PLL circuit, resulted from the conduction start times of the upper and lower operating TRs close to each other and the effect of the faster conduction imposed on the slower conduction, superimposing a compensation electric charge on the output signal by a compensation circuit 37 can completely delete a ripple current.

Filed: 2001-04-27
Abstract: PROBLEM TO BE SOLVED: To provide a device and method, in the failures recovery method relating to multiple layers, for reducing loads of an NMS and minimizing the NMS size in order to deal with the NMS failures and to speed up the failure recovery time. SOLUTION: When failures are detected in multiple layers, each layer's failure detecting/recovering methods 101 and 102 are activated simultaneously and operations are performed until just one phase before a main signal is switched. When any layer the operation of which leads on the phase, through communication end/processing methods 103 and 104 of failure recovery information between layers, informs the other layers accordingly, it stops the other layers' failure recovery operations. The other layers, through the communication end/processing methods 103 and 104 of failure recovery information between layers, respond to the information, and the leading layer on the phase actually switches the main signal based on the result of the other layers' responses.
