    • PURPOSE:To produce an internal clock signal having a higher frequency than an external clock signal and also synchronous with said external clock signal, by providing a PLL circuit to an internal clock circuit. CONSTITUTION:A reference clock signal R (frequency fR) is applied to a frequency multiplying circuit 12 of an integrated circuit 11 from outside or an oscillation circuit OSC13. Then a signal S of a high frequency nfR (n: an integer) which is synchronous with the signal R is produced. A frequency multiplying circuit A consists of a PLL circuit (shown in a figure). The input signals M and N of frequency dividing circuits CNTR1 and 2 function to set the number of divisions respectively. With this internal clock generating circuit, a signal RM of a frequency of 1/M compared with the signal R is equal to a signal SN of a frequency of 1/N compared with the output signal S (frequency fS) of a VCO25 together with phases synchronous with each other. As a result, a signal S of the frequency fS equal to N.fR/M is obtained. Here fS>fR is satisfied with N/M>1. Furthermore the specific constant of an LPF24 is set variable to ensure an action corresponding to a wide range of external clock frequencies.

    • PURPOSE:To operate stably a titled circuit with high accuracy, by providing a capacitor between a connecting point of a high-voltage operating circuit I L circuit, and a ground terminal, so that the noise produced from the I L circuit gives no effect on the high-voltage operating circuit. CONSTITUTION:The noise of clock nature appears at an emitter point A of the I L circuit in incorporating the I L circuit to a constant current part of the power supply side. Then, the capacitor C is connected between the point A and the ground terminal to reduce the noise. Thus, a low-frequency current of an analog circuit hardly flows to the capacitor C, but since the clock noise of a high-frequency current flows through the capacitor C into ground, the noise appearing at an output VA of the analog circuit is reduced remarkably.

    • PURPOSE:To shorten the time from a powering-up point to the start of oscillation by connecting two oscillating circuits composed of I L elements in parallel, and using one oscillating circuit as an oscillating circuit and the other as a bias circuit. CONSTITUTION:A circuit D wherein transistors (TR) 1a and 1b, 2a and 2b, and 3a and 3b each constitute one I L circuit, and a circuit E which has the same element size, the same process and the same circuit constitution are formed closely. A quartz oscillator 4 is connected between the points B and C of the circuit D to constitute an oscillating circuit. On the output side of the circuit E used as a bias circuit, a two-collector TR3a' is used; the collector 31 is connected to the base and to constitute a current mirror circuit, and the collector 32 is connected to the point C of the circuit D. The unbalanced current at the point C increases by 1/(1+beta) time as great as that when the circuit D is used independently and becomes much less, where beta is the current amplification factor of the TR3a', so that an oscillation starting time is shortened.
