Abstract

A novel approach to estimating electromagnetic impulse noise radiated from a digital-circuit board is proposed. It is postulated that there exists a characteristic quantity which represents the noise driving power of a logic gate of a family of ICs. That quantity, a kind of noise unit, is unique for each family, and the total amount of radiated noise from a circuit board is represented by that unit and such factors as the structure of the board, layout, scale of the circuit, and clock frequency. Some results of measurement of noise from some families of ICs are presented. The consistency of the noise unit has been confirmed experimentally for some TTL (transistor-transistor logic) and CMOS families and for clock frequencies up to 10 MHz.
