Abstract: PROBLEM TO BE SOLVED: To output data for which identification re-timing is performed without errors without generating an error in the decision of the identification point of input data even for large duty fluctuation by measuring and recognizing a duty fluctuation amount inside a PLL circuit. SOLUTION: An identification data selection circuit 9 decides the identification point from the leading edge average phase information 108 outputted by a leading edge phase average calculation circuit 7 and duty information 109 outputted by a duty judgement circuit 8 and selects the data corresponding to the decided identification point from phase compared data 102 outputted by a phase comparator circuit 2.

Title: Current control circuit
Inventor: NAKAMU EIJI
IPC: G05F1/56
Filed: 1991-06-21
Abstract: PURPOSE:To improve the efficiency with simple circuitry by composing the current control circuit of a comparator, a driver element, and a delay circuit. CONSTITUTION:A control voltage el is applied to the input terminal of a comparator 1, and an output voltage er of a delay circuit 12 is applied to the other input terminal. When the control voltage el is higher than the output er of the delay circuit 12, the output of the comparator 1 becomes an H level, for example, a driver element 4 is turned on, supplying the current to a load X1. Since this change of current is applied to the delay circuit 12 as a change of the voltage, the output voltage er is increased with the lapse of time. The output of the comparator 1 moves to an L level in the timing of becoming higher than the control voltage el, turning off the driver element 4, and stops the current to the load XL. This current changes causes the reduction of the output voltage er of the delay circuit 12 with the lapse of time. The output of the comparator 1 moves to the H level in the timing becoming lower than the control voltage el.

Abstract: PURPOSE:To increase the film thickness of an oxide film and to lower an impressed voltage by a method wherein, between a source region and a drain region in a semiconductor substrate, the following are formed to be adjacent to each other as a gate insulating film between the semiconductor substrate and a gate electrode: a first part in which the oxide film is formed as a lower layer and a nitride film is formed as an upper layer; and a second part in which the lower layer and the upper layer are reversed. CONSTITUTION:On a channel between a source region 12 and a drain region 13 in a semiconductor substrate 11, the following are formed so as to be adjacent to each other as an insulating film which is laid between the substrate 11 and a gate electrode 16: a first part 17 in which an oxide film 14A is formed as a lower layer and a nitride film 15A (or a dielectric film) is formed as an upper layer; and a second part in which a nitride film 15B (or a dielectric film) is formed as a lower layer and an oxide film 14B is formed as an upper layer. Thereby, since the film thickness of the oxide film can be made large, the oxide film can be formed easily. Since it is not required that an electric charge tunnels through the oxide film, its film quality is not deteriorated. On the other hand, since the nitride film can be made thin, it is possible to lower a voltage which is applied across the gate electrode and the substrate when the electric charge is written or erased.
