摘要： A circuit and a method for interpolative delay is provided. The circuit includes a delay locked loop with interpolation delay. The delay locked loop includes a differential inverter, an interpolation circuit, and a differential compare circuit. The differential inverter is coupled to receive a differential clock signal and coupled to provide an inverted differential clock signal. The interpolation circuit is coupled to receive both the clock signal and the inverted clock signal, and to provide an interpolated clock signal having a first delay relative to the clock signal. The differential compare circuit is coupled to receive the inverted clock signal and coupled to provide a non-interpolated clock signal having a second delay relative to the clock signal. The second delay corresponds to a full delay of the differential inverter and the first delay corresponds to a predetermined fraction of the full delay.

摘要： In a circuit including a number of functional blocks of circuits, each block having a minimum operating voltage, a plurality of sense lines from each of the blocks is used to measure local voltage fluctuation at each block.

摘要： A sample and hold circuit (200) accepts an input (202). During a first half of the clock (204) (either an active high portion or an active low portion) the devices (216, 220, and 222) drive the node (218) to a voltage representative of the voltage present on input (202). At a rising edge of the clock (204), the switch (222) is disabled and the voltage on the node (218) is forced to a higher hold voltage by a capacitor (224). While sample circuit (208) is holding the high voltage on node (218), a hold circuit (210) is settling to a hold voltage representative of the voltage on node (218) in a master-slave fashion. This manner of clocking and controlling the circuit (200) allows circuit (200) to be used in low power, high speed telecommunications systems.

摘要： An overcurrent is detected with small power consumption and at a high level of accuracy. A first transistor section 3 comprised of one NPN transistor 31 and a second transistor section 4 comprised of four NPN transistors 41-44 having the same characteristics as those of the transistor 31 are connected across a current sense resistor 2, with their emitters connected to the resistor 2. The transistors 31 and 41-44 have their bases commonly connected, with a voltage applied between their base and emitter by a voltage application unit 5, and have their collectors connected to transistors 61 and 62 which form a current mirror circuit. Once a bandgap voltage, .DELTA.V.sub.BE, i.e., a voltage difference between the base-emitter voltages of the transistor sections 3 and 4, is determined, the current density ratio of both the transistor sections 3 and 4 is determined, which is used to detect an overcurrent.
