摘要:
A clock signal correction circuit which corrects duty cycle distortions of a clock signal in a simple and accurate way. A frequency divider divides the frequency of a given input clock signal by a natural number n, thereby producing a divided clock signal. The phase of this divided clock signal is identified by a phase detector. By adding an appropriate delay to the divided clock signal according to the identified signal phase, a delay unit produces a delayed divided clock signal. A logical operator creates an output clock signal by performing a logical operation on the original divided clock signal and the delayed divided clock signal.

According to the present invention, a first voltage is generated at a drain of a first MESFET by a first stage circuit that includes a plurality of diode elements and the first MESFET with its gate and drain connected together provided between power sources. The first voltage is applied to a gate of a second MESFET that performs a source follower operation so that a constant second voltage, which is lower by the equivalent of a threshold voltage than the first voltage, is generated at the source. A third MESFET with a diode connection is provided between the second voltage source and a lower power source, and a bias voltage is generated at the drain terminal of the third MESFET. The bias voltage is supplied to the gate of a constant-current transistor, the source of which is connected to the lower power source. The current of the constant-current transistor is supplied to an SCFL circuit, the source of which is connected for common use.
