Abstract
A semiconductor device which continuously outputs data in synchronism with a first clock includes a clock generator which generates a second clock from the first clock which is externally supplied, a flip-flop circuit which operates in synchronism with the second clock, and receives the data, an output buffer circuit which outputs the output data from the flip-flop circuit outside, and a power supply circuit which includes a bandgap reference circuit, generates a voltage controlled by the bandgap reference circuit, and supplies the voltage as a power supply voltage to the clock generator, the flip-flop circuit, and the output buffer circuit.

A semiconductor device which continuously outputs data in synchronism with a first clock, comprising:
- a clock generator which generates a second clock from the first clock which is externally supplied;
- a flip-flop circuit which operates in synchronism with the second clock, and receives the data;
- an output buffer circuit which outputs the output data from the flip-flop circuit outside;
- and
- a power supply circuit which includes a bandgap reference circuit, generates a voltage controlled by the bandgap reference circuit, and supplies the voltage as a power supply voltage to the clock generator, the flip-flop circuit, and the output buffer circuit.
A semiconductor device which continuously outputs data in synchronism with a clock, comprising:
- a clock generator including a delay circuit which delays the clock;
- a flip-flop circuit which operates in synchronism with the clock delayed by the delay circuit, and receives the data;
- and
- an output buffer circuit which outputs the output data from the flip-flop circuit outside,
- wherein a delay time of the delay circuit changes inversely proportional to a frequency of the clock.
