Title: Phase locked loop circuit and phase synchronization method using the phase locked loop circuit
Inventor: OKABAYASHI TETSUYA
IPC: H03L7/199
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To establish a synchronization state in a short time by using a clock error detection circuit and a control voltage comparator circuit so as to detect whether an input clock is normal or in error. SOLUTION: A VCO control voltage outputted from a phase comparator circuit 11 is given to an LPF 12, in which a high frequency component is eliminated and the resulting voltage is outputted as a control voltage (a). The control voltage (a) is given to an A/D converter circuit 13 and a selection circuit 16. A clock error detection circuit 19 detects a state of an input clock and gives the error detection signal to a memory circuit 14 and the selection circuit 16. When it is discriminated that the input clock restores from the erroneous state to the normal state, a control voltage (b) outputted from the A/D converter circuit 13 is compared with a control voltage (c) outputted from the memory circuit 14 by a control voltage comparator circuit 20.  When they are not equal to each other, a phase of an output clock from a VCO 17 controlled by a control voltage (d) is controlled by a frequency divider circuit 18.

IPC: H04B3/54
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a data transmitter where a noise or a loss attended with switching is comparatively less even when a data transmission speed is increased. SOLUTION: A transmission circuit 15 provided to a feeding terminal 1 converts power of a DC power supply E through switching of a transistor(TR) Q0.

In the capacitance variable circuit Cv, a switch element SW1 is turned on/off by a transmission signal outputted from a control circuit 11 to change the capacitance. Thus, a transmission signal whose ripple changes corresponding to the transmission signal is sent to a signal line 3.  Since a signal value is represented by the amplitude of the ripple, the frequency of the transmission signal can be higher than a cut-off frequency of the low pass filter and the frequency of the transmission signal is increased without increasing the switching frequency of the TR Q0 to enhance the data transmission speed.
