    摘要: A CMOS differential amplifier uses a first pair of complementary MOSFETs and a second pair of complementary MOSFETs coupled to a power supply (by another pair of MOSFETs) in such a manner as to be self-biasing and have improved channel-length modulation characteristics. An N-type MOSFET couples the first and second complementary MOSFET pairs to ground potential via a first resistor, and a P-type MOSFET couples the first and second complementary MOSFET pairs to a power-supply via a second resistor. The first and second resistors can be provided using non-salicided N-type MOSFET resistors. The third N-type MOSFET preferably has a low-threshold voltage, including a zero-threshold voltage, and the substrates of the P-type MOSFETs in the first and second complementary pairs are further preferably connected to the sources of those MOSFETs in order to reduce body-sensitivity effects.

    摘要: A decoupling capacitor and protection circuit is provided that will assist the power supply network in stabilizing the voltage near circuits that demand short rapid transitions in electrical current. The protection circuit also significantly reduces the amount of electrical current drawn by defective large area decoupling capacitors. An inverter stage controls a switching circuit connected in series with a decoupling capacitor. A feedback circuit is provided from the output of the capacitor to the switching circuit. If the capacitor goes bad, then a voltage is present on the feedback circuit and the switching circuit ensures that the output of the failed capacitor is presented with an open circuit so that the short circuit current flow through the capacitor is eliminated. In this manner, the integrity of the other circuits located near the failed capacitor will operate appropriately.

    摘要: A method, system, and product are disclosed for determining a voltage drop across an entire integrated circuit package. A geometric description of the entire integrated circuit package is determined. The description is subdivided into non-uniform areas. A resistance of each one of the non-uniform areas is determined. A resistive netlist of the entire integrated circuit package is then determined by combining the resistance of each one of the non-uniform areas. The package is then simulated utilizing the netlist to determine the voltage drop across the entire integrated circuit package.

    摘要: An apparatus and method for determining power consumption in logic devices including mixed static and dynamic logic blocks is implemented. Input logical signals are tagged as having dynamical behavior or static behavior, and the power consumption of the logic block determined according to the behavior of the input signal. If an input signal has dynamic behavior, an output signal making a transition in response thereto will make two transitions per clock cycle, and the per cycle power consumption of the logic block is accordingly weighted. In another embodiment, a Boolean behavior signal is calculated for each block from clock phase tags and “one cycle per cycle” circuit level simulations. The per cycle power consumption of each logic block receives a weight in response to the Boolean behavior signal, according the behavior of the block characterized thereby.

    摘要: A method, an apparatus, and a computer program are provided to measure and/or correct duty cycles. Duty cycles of various signals, specifically clocking signals, are important. However, measurement of very high frequency signals, off-chip, and in a laboratory environment can be very difficult and present numerous problems. To combat problems associated with making off-chip measurements and adjustments of signal duty cycles, comparisons are made between input signals and divided input signals that allow for easy measurement and adjustment of on-chip signals, including clocking signals.

    摘要: This invention reduces pessimism in cross talk analysis of digital circuits by combining only the peak noises from aggressor nets that can switch simultaneously during the time interval when the downstream receiving latch can sample the errant data. This is done by, first, determining aggressor switching windows and victim sensitivity windows. These windows are then used to determine which combination of noise sources can temporally align so as to cause the greatest noise within the victim sensitivity window.
