    摘要: Overvoltage protection circuits include a pass transistor having first and second current carrying terminals electrically connected to an input signal line and an output signal line, respectively, and a voltage clamping circuit. The voltage clamping circuit is electrically connected to a power supply line and a gate of the pass-transistor and dynamically clamps a capacitively bootstrapped voltage at a gate of the pass transistor within a first range so that the output voltage as well as the magnitudes of all gate-to-source, gate-to-drain and drain-to-source voltages across the pass transistor and all transistors within the voltage clamping circuit do not exceed a level in excess of about Vdd when Vin=2Vdd, where Vin equals a voltage of an input signal applied to the input signal line and Vdd equals a power supply voltage on the power supply line.

    摘要: A power supply rejection circuit and method thereof for capacitively-stored reference voltages is disclosed. The power supply rejection circuit generally comprises a comparison circuit for comparing a signal associated with a power supply such as, for example, a Wheatstone bridge configuration, to a stored reference voltage, such that the comparison circuit includes at least one existing capacitor therein. At least one additional capacitor can be then coupled to the comparison circuit, such that the additional capacitor creates a capacitively-coupled voltage divider. This capacitively-coupled voltage divider negates the first order effects of power supply noise in the system. This effect significantly reduces the effect of power supply noise and improves signal jitter associated with the comparison circuit during a comparison of the signal to the stored reference voltage utilizing the comparison circuit.

    摘要: Electrostatic Discharge (ESD) protection scheme includes a divided rail structure to route damaging ESD away from sensitive circuitry. Specifically, Vdd and Vss rails are divided to segregate the ESD current within a circuit, thus isolating the sensitive circuitry from ESD exposure. In an exemplary embodiment, Vdd is divided into Vdd-esd and Vdd core, while Vss is divided into Vss-esd and Vss core. The structure in cooperation with diodes, clamps and resistors enables to isolate the rails (Vdd core and Vss core) associated with sensitive circuitry from ESD current.

    摘要: An ESD protection circuit includes a SCR and a switching means, such as a MOS transistor connected to the SCR so that the SCR is turned on by the switching means to allow an ESD pulse to pass from a Pad line to a grounded VSS line and thereby dissipate the ESD pulse. The SCR is connected between the Pad line and the VSS line. One MOS switching means is connected between the Pad line and the SCR and has a gate which is connected to a VDD line which maintains the switch in open condition during normal VDD bias conditions. An ESD pulse applied to the Pad line, the switch is preconditioned in ON mode allowing the SCR to be predisposed to conduction to allow the ESD pulse to flow to the VSS line.

    摘要: An integrated circuit that includes I/O circuitry that may or may not be protected from ESD damage. The protection from ESD damage may be selectively deactivated or activated or may not be present at all in one or more of the I/O circuits. In use, the integrated circuit may be coupled to another integrated circuit to form a multi-chip module where the ESD protection for the I/O circuitry between the modules is deactivated or not present. This is advantageous because the likelihood of ESD damage to this I/O circuitry is reduced once the multi-chip module is formed. It is to be understood that both the foregoing general description and the following detailed description are exemplary, but are not restrictive, of the invention.
