摘要： A master latch (1) is formed from a static circuit, and a slave latch (2) is formed from a dynamic circuit. The number of circuit elements can be smaller as compared to a slave latch formed from a static circuit so that the size and area of a master-slave flip-flop can be reduced. Since the master latch is formed from a static circuit, data can be held stably during the standby time by setting the master latch in a data holding state.

摘要： A structure (113b) which includes an overhang and a support portion supporting substantially the center of the overhang, and in which the area of the support portion is smaller than the area of the overhang in the two-dimensional direction of an upper electrode (1110b) is formed on the upper electrode (110a) in a region above each lower electrode 105a in one-to-one correspondence with the lower electrode (105a). An object of surface shape sensing, e.g., the tip of a finger (1602) touches the surface of the overhang of the structure (113b), and the support portion of the structure (113b) whose overhang is in contact with the object of sensing pushes down a portion of the upper electrode (110a) toward the lower electrode (105a), thereby deforming the upper electrode (110a).

摘要： A first control potential setting means (1) generates a first control potential (N2) which reverses the magnitude relationship with a second control potential (N3) when an input signal (IN) reaches the vicinity of a logical threshold value. A second control potential setting means (2) generates the second control potential (N3) which changes in the same direction as the input signal (IN), in accordance with a change in input signal (IN). An output means (3) includes transistors (Q5, Q6), and generates an output signal (OUT) having a predetermined potential on the basis of the first control potential (N2), the second control potential (N3), and a reset signal (RSET). A reset means (4) turns off the transistor (Q6) while a waveform shaping circuit is in operation.

摘要： A small capacitance change detection device includes a capacitance detection element, signal generation circuit, signal amplification circuit, and output circuit. The signal amplification circuit includes a first transistor and first to third voltage sources. The second or third voltage source is connected to the other output terminal of the first transistor via a first switch. A voltage to be applied from the second voltage source to the other output terminal is set to have a value equal to or larger than a value obtained by subtracting a threshold voltage of the first transistor from a voltage of the first voltage source while a voltage to be applied from the third voltage source to the other output terminal is set to have a value equal to or smaller than a value obtained by subtracting the threshold voltage from the voltage of the first voltage source. The output circuit is connected to a connection point between the other output terminal of the first transistor and the first switch and, after a voltage of the second or third voltage source is applied to the connection point in an ON state of the first switch, receives the voltage at the connection point on the basis of an OFF state of the first switch and charge control by the signal generation circuit after the first switch is turned off.

摘要： A surface shape recognition apparatus includes a plurality of sensor electrodes, passivation film, capacitance detection circuit, and ground electrode. The sensor electrodes are formed on an interlevel insulator on a substrate and insulated from each other. The passivation film is formed on the interlevel insulator to cover the upper and side surfaces of each sensor electrode. The passivation film is formed from a dielectric material. When a target recognition object comes into contact with the surface of the passivation film, the capacitance detection circuit detects an electrostatic capacitance formed between the sensor electrode and the surface of the target recognition object opposing the sensor electrode. The ground electrode passes static electricity on the surface of the passivation film.
