Title: Synchronizing circuit
Inventor: FUKUDA MINORU
IPC: H03K5/00
Filed: 1984-09-19
Abstract: PURPOSE:To synchronize also signals having different frequency in addition to signals having the same frequency by arranging a reference signal frequency divider and a non-reference signal frequency divider both of which regard the ratio of the frequency of a reference signal to that of a non-reference signal as their frequency dividing ratio on the prestage of a phase comparator. CONSTITUTION:When the phases of a reference signal f3 and a non-reference signal f4 are shifted each other, the phase shift of both the signals appears also in a reference signal f3' and a non-reference signal f4' which are divided by frequency dividers 8, 9 respectively. Consequently, the phase comparator 2 can detect the phase difference between the reference signal f3' and the non- reference signal f4' a as the phase difference of signals having the same frequency similarly to the ordinary method and sends a signal corresponding to the phase difference to a phase difference/voltage converter 3. The converter 3 generates a voltage corresponding to said phase difference and sends the voltage to a delay unit 1. Receiving the voltage corresponding to the phase difference, the delay circuit 1 shifts the phase of the non-reference signal f4 by a prescribed value to synchronize the non-reference signal f4 with the reference signal f3.

IPC: H01L21/338
Filed: 1986-08-22
Abstract: PURPOSE:To realize an ultra-high-speed operation by a method wherein a cyclic structure is provided along at least one layer among a semiconductor layer, an insulating layer and a conductive layer and, at this cyclic structure, the effective mass of an electron which is related to the movement in the direction along the direction of this layer can be either positive or negative depending on the energy of the electron. CONSTITUTION:The cross section parallel to the source-drain direction, i.e., the channel direction, at an n type GaAs layer 6 is shaped like a cyclic structure along the same direction. The concentration of electrons in a two-dimensional electron layer 12 appearing near the interface between an undoped GaAs layer 4 and an n type Al0.3Ga0.7As layer 5 is modulated by the cycle, and the potential applied to these electrons becomes a cyclic potential. If a gate voltage is scanned at this time, the Fermi level is increased gradually and reaches an inflection point as shown by A, A', B, B', etc. Before and after the inflection point the effective mass of the electron changes from a positive state to a negative one. Therefore, when the Fermi level passes through the inflection point, the electron which has been accelerated so far is affected by the acceleration acting in the reverse direction and the speed is slowed down.
