摘要： PURPOSE:To eliminate positive/negative pulse noise included in a rectangular wave signal by providing a delay circuit and a gate circuit receiving a rectangular wave data signal and a clock and generating a fetch signal at the trailing or leading of a prescribed number of order of clock from a high-low change of a signal. CONSTITUTION:The rectangular wave signal (data input) is outputted through a delay circuit 16, which is controlled by a data input (b) and a clock (a) by an inverter 18, NAND gates 20, 22, 24, 10 and frequency division circuits 12, 14. Since the delay circuit 16 fetches the H, L level of the data input (b) when the clock descends, e.g., twice depending on the H, L change of the data input (b), the noise having a pulse width shorter than the two trailings of said clock, either positive or negative, is not fetched and but neglected.

摘要： The flip-flop circuit includes: a series (8) circuit which has a negative differential resistance element (1) and another negative differential resistance element (2) that has a control terminal capable of controlling a value of an element current; a transfer gate (9); a latch circuit (10) which has negative differential resistance elements (4), (5) connected in series; and an inverter circuit (11) which has an FET (6) as a drive element and a negative differential resistance element (7) as a load element. With this, such a flip-flop can be obtained that when a clock signal (CLK) is applied to a power supply terminal DD1 of the series circuit (8) and a control terminal of the transfer gate (9) and an input signal (IN) is supplied to the control terminal of the negative differential resistance element (2), an output is placed at a terminal.

摘要： An integrated circuit includes an upper threshold circuit, a lower threshold circuit, and a control circuit. The upper threshold circuit is configured to set a logic level of a first enabling signal based on comparing an input voltage signal with an upper threshold voltage. The lower threshold circuit is configured to set a logic level of a second enabling signal based on comparing the input voltage signal with a lower threshold voltage. The control circuit is configured to change an output voltage signal from a first voltage level to a second voltage level when the logic level of the first enabling signal and the logic level of the second enabling signal are changed consecutively.
