摘要： An inductor-capacitor phase locked loop (LCPLL) includes an inductor-capacitor voltage controlled oscillator (LCVCO) that provides an output frequency. A calibration circuit includes two comparators and provides a coarse tune signal to the LCVCO. The two comparators respectively compare the loop filter signal with a first reference voltage and a second reference voltage that is higher than the first reference voltage to supply a first and second comparator output, respectively. The calibration circuit is capable of adjusting the coarse tune signal continuously in voltage values and adjusts the coarse tune signal based on the two comparator outputs. A loop filter provides a loop filter signal to the calibration circuit and a fine tune signal to the LCVCO. A coarse tune frequency range is greater than a fine tune frequency range.

摘要： A level shifter includes an input node, an output node, a pull-up transistor, a pull-down transistor, and at least one diode-connected device coupled between the pull-up transistor and the pull-down transistor. The level shifter is arranged to be coupled to a high power supply voltage, to receive an input signal having a first voltage level at the input node, and to supply an output signal having a second voltage level at the output node. The high power supply voltage is higher than the first voltage level. The at least one diode-connected device allows the output signal to be pulled up to about a first diode voltage drop below the high power supply voltage and/or to be pulled down to about a second diode voltage drop above ground. The first diode voltage drop and the second diode voltage drop are from the at least one diode-connected device.

摘要： Some aspects of the present disclosure provide for a method of automatically balancing mask misalignment for multiple patterning layers to minimize the consequences of mask misalignment. In some embodiments, the method defines a routing grid for one or more double patterning layers within an IC layout. The routing grid has a plurality of vertical grid lines extending along a first direction and a plurality of horizontal grid lines extending along a second, orthogonal direction. Alternating lines of the routing grid in a given direction (e.g., the horizontal and vertical direction) are assigned different colors. Shapes on the double patterning layers are then routed along the routing grid in a manner that alternates between different colored grid lines. By routing in such a manner, variations in capacitive coupling caused by mask misalignment are reduced.
