Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To generate an address that is needed to efficiently process FET operation that has a large point number by using base number two to five address generating circuits by combining them. SOLUTION: The base number of a 1st stage is set to five, the base number of a 2nd stage is set to four, the base number of a 3rd stage is set to three and the base number of a 4th stage is set to two respectively, and a read address to coefficient memory is created. When address generation due to a base number of a certain stage finishes, address generation due to a base number of the next stage is started in the timing. With this, each stage is made pipeline connection and addresses are generated. When a clock that is generated by a system clock and each counter is inputted, cumulative addition circuits 10 and 20 perform cumulative addition operations from an initial value. Outputs 1×CL of a multiplication circuit 40 become 0, 6, 12, 18,.... In such cases, a selector 70 selectively outputs each output of the circuit 40 in accordance with an output content of the circuit 20.

Inventor: OGATA HIROTAKA
IPC: G06F1/32
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of a semiconductor device which has a differential input buffer between itself and an external interface circuit. SOLUTION: The semiconductor device has a differential input buffer 1 and a latch circuit 2 having its input connected to the output of the differential input buffer. The differential input buffer 1 has a differential input amplifier which inputs a reference potential Vref and an external signal IN differentially, a power switch Q5 which supplies a high-potential side current to the differential amplifier, and a 2nd power switch Q6 which supplies a low-potential side current to the differential input amplifier.  A control circuit 3 controls the differential input buffer 1 into alternate active and inactive states according to the state of a synchronizing clock signal QCLKb and also controls the latch circuit 2 into input and latch states synchronously, so a through current is prevented from always passing through the differential input buffer 1, thereby reducing the power consumption of the semiconductor device.

Filed: 1989-03-20
Abstract: PURPOSE: To extremely exactly apply a desired delay time with a low noise to a sine wave signal by providing an adder means, phase shift means, and amplitude control means. CONSTITUTION: An SAW oscillator 10 generates a sine wave, and a current amplifier 12 generates a waveform whose phase is synchronizing, and a current amplifier 14 generates a waveform whose phase is shifted 90 deg..

For example, they are phase-shifted only at 45 deg. to the output signal of the ooscillator 10. The outputs of the amplifiers are added by an adder 20, and an output waveform is obtained. A desired time delay can be obtained by relatively changing the amplitude of the two input signals of the adder 20, and any one of the amplifiers is sufficient for this processing. Thus, the desired delay time with a low noise can be extremely exactly applied to a sine wave signal.
