    摘要: A protection circuit apparatus comprises an electrostatic discharge circuit coupled to an isolation filter. The isolation filter comprises an inductor coupled to a ground-coupled capacitor, the inductor and the capacitor being coupled to the electrostatic discharge circuit. The inductor is also coupled to an electrostatic discharge sensitive device to be protected from an electrostatic discharge event.

    摘要: An electrostatic discharge (ESD) protection circuit (40) is coupled across input-output (I/O) pads (21) and common terminals (24) of a core circuit (22) to protect it from ESD events. The circuit (40) comprises, a unidirectional ESD clamp (23) and two or more floating diodes (42, 44) arranged in parallel opposed configuration in series with the ESD clamp (23), the combination coupled between the I/O pads (21) and the reference terminals (24). In a preferred arrangement, the two strings of opposed parallel coupled diodes (42, 44) are used with different numbers of diodes in each string. These diodes (42, 44) operate in forward conduction (43, 45), so the energy dissipated therein during an ESD event is much reduced compared to a reverse biased diode and they can have smaller area. Signal clipping at the I/O pad (21) is reduced, less power is dissipated and less chip area is utilized.

    摘要: In a system comprising a plurality of gain elements configured in parallel to one another, a harmonically tuned filter provides an isolation circuit to prevent odd-mode differential oscillations. A harmonically tuned filter comprises resistors, inductors, and capacitors (RLC) to selectively allow one or more specific harmonics to pass through the isolation circuit to suppress the odd-mode oscillation. Direct current (DC) and other non-harmonically-related frequencies do not pass through the isolation circuit. Since the resistor is used to dissipate specifically the energy of the harmonic frequencies causing the odd-mode oscillation, the current density through the resistor is much lower than the current density of a typical odd-mode resistor without a harmonically tuned filter.
