A voltage-controlled oscillator has a feedback circuit connected to the gate of a transistor which controls a current flowing through an oscillation unit. The feedback circuit applies a voltage depending on the DC voltage of an oscillated signal to the gate of the transistor. When the oscillated signal is reduced in level to lower the DC voltage, the feedback circuit lowers the voltage applied to the gate of the transistor. The current flowing through the oscillation unit is reduced to increase the level of the oscillated signal. When the oscillated signal is increased to increase the DC voltage, the feedback circuit increases the voltage applied to the gate of the transistor. The current flowing through the oscillation unit is increased to reduce the level of the oscillated signal. The feedback process prevents the voltage-controlled oscillator from operating unstably regardless of manufacturing variations of transistors from design values.

In a multiplexor, respective outputs of two latches alternately brought into a dynamic holding condition at phases opposite to each other, respectively, are connected in common in a wired connection. Thus, a selector becomes unnecessary, with the result that the number of transistors driven with a clock signal can be reduced, and the electric power consumption is correspondingly reduced.

A dynamic latch circuit or a dynamic flip-flop circuit of the present invention includes a transfer gate to be controlled by a clock and provided with a complementary configuration using a P-channel and an N-channel MOS (Metal Oxide Semiconductor) transistor. The transfer gate allows the individual node included in the circuit to fully swing between a high potential power source and a low potential power source. This causes a minimum of decrease to occur in an ON current for driving the respective node and thereby realizes high-speed operation. Further, the balance of the rising time and falling time of an output signal is improved, reducing the deviation of the duty of the output signal from 50%. The circuit is therefore operable with sufficient operation margins at positive- and negative-going edges. Consequently, the entire macrocircuit using the circuit of the present invention can have its operation frequency and therefore power consumption lowered.
