Patent number: 7148735Abstract: In a level shifter, in the case where the amplitude voltage of an input signal (i.e., a first power voltage VDDL) input to an input terminal is changed to be higher and the amplitude voltage of an output signal (i.e., a second power voltage VDDH) output from an output terminal is changed to be lower, a fall delay time of the signal output from the output terminal tends to be longer than a rise delay time of the signal. However, an inverted input signal obtained by an inverter is input to a level shifting unit and also to the gate of an N-type transistor, and therefore, the N-type transistor is turned on at the fall of the input signal input to the input terminal, so as to supply a current based on the second power voltage VDDH to an output node of the level shifting unit for assisting the shift into H level performed in the level shifting unit.Type: GrantFiled: July 28, 2005Date of Patent: December 12, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Miwa Ito, Kazuyuki Nakanishi, Akio Hirata, Hiroo Yamamoto, Tsuguyasu Hatsuda

Patent number: 6853228Abstract: In a flip-flop circuit which includes an input section using a dynamic circuit and an output section using a static circuit and which captures data during a period of a pulse width shorter than a clock cycle, the number of transistors, circuit area and power consumption are reduced. In FIG. 1, an output signal of an inverter circuit INV1 constituting a latch circuit 2 connected to the output terminal of an input section 1 is used as an input signal of a control section 3. Thus, a control signal output from the control section 3 to the input section 1 is stabilized, thereby suppressing unnecessary operation of circuit elements and reducing unnecessary power consumption. In addition, the configuration of the control section 3 is simplified. As a result, the number of transistors constituting the circuit and the circuit area can be reduced.Type: GrantFiled: October 17, 2003Date of Patent: February 8, 2005Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Akio Hirata, Masahiro Gion, Kazuyuki Nakanishi
