    摘要: An apparatus for controlling slew rate is coupled to two adjustable voltage rails. The output of the apparatus is coupled to the gate of a switching element. By employing two adjustable voltage rails, the slew rate of the switching element is proportional to the voltage difference between the first adjustable rail and the second adjustable rail. The slew rate control apparatus can be applied to a variety of switching elements including N channel Field Effect Transistors (NFETs), P channel Field Effect Transistors (PFETs), current mode logic circuits and level shifter circuits.

    摘要: A level shifter receives an input voltage signal and produces an output voltage signal. The level shifter includes a first inverter, configured to operate at a potential difference between a first voltage V1 and a second voltage V2. The output from the invert is capacitively coupled to an input of a latch circuit via a capacitor. The capacitor has a first terminal connected to the output terminal of the first inverter, and further has a second terminal. The level shifter has a resistor connected to a third voltage V3 and to the capacitor for tying the input to the latch circuit to a desired voltage. The latch circuit is configured to operate at a potential difference between a fourth voltage V4 and a fifth voltage V5. The latch has an input node connected to the resistor and the capacitor, and further has an output node connected to an output node of the level shifter.

    摘要: One or more techniques for buffer offset modulation or buffer offset cancelling are provided herein. In an embodiment, an output for a sigma-delta analog digital converter (ADC) is provided using an output of a first chop-able buffer (FB) and an output of a second chop-able buffer (SB). For example, the output of the FB is associated with a first offset, the output of the SB is associated with a second offset, and the output of the ADC includes an ADC offset associated with the first offset and the second offset. In an embodiment, buffer offset modulation is provided by modulating the ADC offset using an offset rotation. In an example, the offset rotation is based at least in part on a reference clock and the output of the ADC. The buffer offset modulation mitigates the first offset or the second offset, where such offsets are generally undesired.

    摘要: A current cell array includes a number of current cell groups arranged such that they extend in a first direction. Each of the current cell groups is identified by a first identifier that increases in a direction of a gradient across the current cell array. A number of current cells are included in each of the current cell groups. Each of the current cells is identified by a respective second identifier that increases in the direction of the gradient across the current cell array. The current cells are positioned in the current cell groups based on the first and second identifiers.
