Title: Bootstrap circuit
Inventor: MIYATAKE HIDEJI
IPC: G11C11/407
Filed: 1985-11-13
Abstract: PURPOSE:To prevent the occurrence of signal delay when bootstrapped by raising the gate voltage of a switching transistor of a switched capacitor circuit and making it operate in the area of a triode. CONSTITUTION:In the switched capacitor circuit 100 of a bootstrap circuit, word line driving voltage RXP is bootstrapped by power source voltage through a bootstrap transistor Q22 and a capacitor 4. At this time, voltage RXB higher than power source voltage is supplied to a capacitor C3 which does not become word line load together with a capacitor 4. The potential of a node N8 is made to about double the power source voltage. This high potential is supplied to a base and the transistor Q22 is controlled, and a transistor Q21 operates in the triode area. Accordingly, it is not necessary to operate the transistor Q22 in a saturated area as in a case where capacitors C3, C4 are used in common, and the occurrence of delay of bootstrapped signals can be prevented.

Title: Digital phase locked loop circuit
Inventor: SENOO TAKANORI
IPC: G05D13/62
Filed: 1986-10-29
Abstract: PURPOSE:To accurately keep frequency and phase by providing an automatic phase shifting circuit which switches and selects the outputs of a ring counter by a frequency control signal obtaining the phase difference signal received from a phase comparator through a loop filter. CONSTITUTION:Such a digital phase locked loop circuit consists of a phase comparator 1, a loop filter 2, an m-notation ring counter 3 and an automatic phase shift circuit 4. The value obtained by integrating the phase difference signal outputted from the comparator 1 via a filter 2 is turned into a frequency control signal and supplied to the circuit 4. Thus the frequency of a clock K is kept at a constant level. The circuit 4 shifts phase so that the frequency of the clock K is increased with a phase delay of the phase difference signal and decreased with a phase advance, respectively. Thus it is possible to accurately keep the frequency and the phase of an input signal.

Abstract: PURPOSE:To prevent the sudden change of a clock signal frequency and to smoothly perform a reproducing action by providing a frequency shift control circuit and gradually shifting and switching the clock frequency. CONSTITUTION:The frequency shift control circuit 100 is provided in a clock signal generation circuit 7. In the case of switching a fixed frequency clock signal generation circuit 8 to a variable frequency clock signal generation circuit 9, the output frequency of the circuit 9 is switched to the output frequency of the circuit 8 by the 1st switching control circuit 101 of the circuit 100 and the circuit 8 is switched to the circuit 9 by a 1st switch S1, then the output frequency of the circuit 9 is gradually changed to be shifted. Meanwhile, in the case of switching the circuit 9 to the circuit 8, the output frequency of the circuit 9 is gradually changed to be shifted by operating a 2nd switch S2. When it coincides with the output frequency of the circuit 8, the circuit 9 is switched to the circuit 8 through the switch S1. With such constitution, the sudden change of the clock signal frequency is prevented and the reproducing action is smoothly performed.
