Patent JP-H02128518-A (JP)
Title: Semiconductor logic circuit
Inventor: YAMASHITA SEIYA
IPC: H03K19/0948
Filed: 1988-11-08
Abstract: PURPOSE:To change the logical level of an output signal with a short delay in accordance with the logical level change of an input signal by connecting a load capacity to the channel connection point between a first MOS transistor TR and a second MOS TR. CONSTITUTION:A capacitor C1 is connected between drains of TRs QN1 and QN2 and the ground. When an input signal phi1 goes to the high level at a time t1, a TR QP1 is turned off and the TR QN1 is turned on, and the charge in the capacitor C1 is discharged through the TR QN1 from a time t2 to a time t3. When an input signal phi2 goes to the high level at a time t4, a TR QP2 is turned off and the TR QN2 is turned on. Since a circuit is so operated that the capacitor C1 is charged with the electric charge at a nodal point X1 at this time, an output signal phi3 quickly goes to the low level. Thus, the logical level of the output signal is changed with a short delay correspondingly to the logical level change of the input signal.

Title: Method and system for optimizing digital filter
Inventor: IKEDA KAZUJI
IPC: G06F17/50
Filed: 1990-10-22
Abstract: PURPOSE:To automatically optimize a signal flow diagram by including a factorization process in which factorization is applied to an approximate integer expressed in the sum of a power on 2, and applying the factorization process to the approximate integer and a remainder generated from the approximate integer repeatedly. CONSTITUTION:In a maximum coefficient word length decision process 21, relation 1/2L<-1>=2<->X/¦a¦ is set assuming the strict value of a filter coefficient as (a), and the input signal word length of a filter as L by connecting an input quantization error to an error due to coefficient quantization with a code as stated above, and the integer part of (x) goes to the maximum coefficient word length (k). Thence, in an approxima tion process 22, the approximation of the filter coefficient (a) is performed by [a*2<k>]4/5/2<k> to express the filter coefficient by coefficient accuracy of 2<-k>. In such a case, [ ]4/5 represents the half-adjust of digits less than a decimal point, and reduc tion of fraction is performed afterward. When a numerator is developed to the sum of the power on 2, the optimum development can be performed so as to reduce the number of items to a minimum by performing the factorization process 24 in which the factorization of an integer is applied to the nearest remainder of the power on 2. In such a way, it is possible to obtain targeted frequency characteristic and S/N.
