摘要:
A switched-capacitor filter provided with, at its input stage, a prefilter comprised only of a plurality of additional switched capacitors together with a switched capacitor common to the switched-capacitor filter. The switched capacitor common to the switched-capacitor filter is driven by primary clock pulses having a period T, while the additional switched capacitors are sequentially driven by secondary clock pulse groups. Each of the secondary clock pulse groups has the same period T, and the phases of the second clock pulse groups are shifted by T/2.sup.k, 2T/2.sup.k, 3T/2.sup.k . . . (2.sup.k -1)T/2.sup.k with respect to the first clock pulses (k is a positive integer). The sampled and held signals in the switched capacitors are supplied synchronously to the switched-capacitor filter.

A switched capacitor filter having at its input, a signal converter for creating so-called 100% sample and hold signals. The signal converter comprises a plurality of switched capacitors. The switched capacitors, connected in parallel with each other, receive the same successive input signals and supply the so-called 100% sample and hold input signals to the switched-capacitor filter. The switched capacitors, on one hand, charge each of said input signals sequentially and, on the other hand, alternately discharge the respective stored input signals one by one.
摘要:
A phase-locked loop circuit provides a phase comparator which receives input signals through a first input terminal, a loop filter which receives a first output and a second output of the phase comparator, and a voltage-controlled oscillator which produces output signals of an oscillation frequency proportional to the first output and the second output of the loop filter. The signals corresponding to the output signals produced by the voltage-controlled oscillator are supplied to a second input terminal of the phase comparator so that the phase of the signals supplied to the first input terminal of the phase comparator is compared with the phase of the signals supplied to the second input terminal. In the present invention, the loop filter comprises a first capacitor connected to the output terminal of the loop filter, second and third capacitors, each having a terminal connected to the output terminal of the loop filter, and a charging circuit for electrically charging the first, second, and third capacitors. The charging circuit is connected in parallel with the second capacitor. A discharging circuit for discharging the first, second, and third capacitors is connected in parallel with the third capacitor.

摘要:
The clock synchronization accuracy between a master node and a slave node is stably measured. The slave node synchronizes its own clock with the clock of the master node by means of the packets transmitted from the master node. It reproduces the clock of the slave node by means of the transmitted packets, accumulates information on the transmitted packets and the clock of the slave node and performs clock synchronization on the basis of the accumulated information.
