    Abstract: A circuit has a first circuit module including a first resistor and first and second transistors coupled in parallel with the first resistor. The first resistor and the first and second transistors are coupled together at a first node. An equivalent resistance across the first circuit module increases as a voltage of the first node is increased from a first voltage to a second voltage, and the equivalent resistance across the first circuit module decreases as the voltage of the first node is increased from the second voltage to a third 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 Decision Feedback Equalizer (DFE) with programmable taps includes a summer configured to receive a DFE input signal. Delay elements are coupled to the summer. The delay elements are connected in series. Each delay element provides a respective delayed signal of an input signal to the delay element. A weight generator is configured to provide tap weights. The DFE is configured to multiply each tap weight to the respective delayed signal from the respective delay element to provide tap outputs. Each tap output is selectively enabled to be added to the summer or disabled based on a first comparison of a first threshold value and each impulse response or each tap weight corresponding to the respective tap output, where the impulse response is the DFE input signal in response to a pulse signal transmitted through a channel.
