Abstract: A sensing circuit includes a sensing resistor, a reference resistor and a comparator. The comparator has a first input coupled to the sensing resistor, a second input coupled to the reference resistor, and an output. The first input is configured to be coupled to a data bit line associated with a memory cell to receive a sensing input voltage caused by a cell current of the memory cell flowing through the sensing resistor. The second input is configured to be coupled to a reference bit line associated with a reference cell to receive a sensing reference voltage caused by a reference current of the reference cell flowing through the reference resistor. The comparator is configured to generate, at the output, an output signal indicating a logic state of data stored in the memory cell based on a comparison between the sensing input voltage and the sensing reference voltage.

Abstract: 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.

Abstract: A current value of a first pixel and/or a current value of a second pixel of a display are adjusted until a value of a current difference is acceptable. The current value of the first pixel corresponds to a brightness level of the first pixel. The current value of the second pixel corresponds to a brightness level of the second pixel. Adjusting the current value of the first pixel involves adjusting a threshold voltage value of a transistor of the first pixel. Adjusting the current value of the second pixel involves adjusting a threshold voltage value of a transistor of the second pixel.

Abstract: A method of sharing inductors for inductive peaking of an amplifier having at least two stages includes calculating a single stage inductance of a single stage of the at least two stages for inductive peaking in order to have a stable impulse response. A shared inductance is calculated for inductive peaking by dividing the single stage inductance by a number of stages of the at least two stages. At least two inductors having the shared inductance are shared among the at least two stages for inductive peaking.

Abstract: A method of operating a voltage regulator circuit includes generating a control signal by an amplifier of the voltage regulator circuit. The control signal is generated based on a reference signal at an inverting input of the amplifier and a feedback signal at a non-inverting input of the amplifier. A driving current flowing toward an output node of the voltage regulator circuit is generated by a driver responsive to the control signal, and the driver is coupled between a first power node and the output node. The feedback signal is generated responsive to a voltage level at the output node. A transistor, coupled between the output node and a second power node, is caused to operate in saturation mode during a period while the voltage regulator circuit is operating.
