Filed: 1998-08-24
Granted: 2000-06-11
Abstract: The method for mixing various signals is to first take n samples Si(tj) (I I=1,2, iKm; j=1,2,iKn) from m to-be-mixed signals Si(t) in [T0, T1], where m is a positive integer, t is in the interval [T0, T1]; T0, T1 are real numbers; t is the time variable. Second, a function set {iaj(t) [I I=1,2,iKm; j=1,2,iKn]}is selected and iaj (t) in [T0, T1] is linearly independent. Finally, the transformation function Soi (t) = summation from j=1 to n for [iaj(t)Sj(t)j] is established. All of the Soi(t) are added to obtain the SM(t) = summation from I I=1 to m for [Soi(t)]; therefore, the SM(t) is the transformation mixed signal after mixing. The method to separate the signals is as follows. The foregoing SM(t) contains m x n samples Si(tj)(I I=1,2,iKm; j=1,2,iKn); each sample has a coefficient of iaj(t). Using the mutually exclusive characteristics of the iaj(t), m x n independent equations with Si(tj) unknowns are established. Finally, the simultaneous equations are solved to obtain Si(tj).

Granted: 2001-06-16
Abstract: A semiconductor device with an electrostatic discharge (ESD) protective circuit is disclosed. In this semiconductor device with an ESD protective circuit, an n-well guard ring is formed around an NMOS field transistor of a data input buffer or around an NMOS transistor of a data output buffer. The n-well guard ring is strapped to an n-well of a PMOS field transistor and to an n-well of a PMOS transistor, and thus a PNPN path is formed toward the PMOS transistor at a positive mode of the ground voltage. Therefore, the electrical resistance between the wells of the NMOS transistors and the PMOS transistors can be reduced, thereby improving the characteristics of the ESD protective circuit and a latch-up device. Further the layout area is reduced, and thus, the characteristics and the reliability of the semiconductor device are improved.
