    Abstract: Variable-gain amplifiers (VGAs) and/or continuous-time filters (CTFS) are implemented with circuitry that provides improved power-supply rejection. The power-supply rejection circuitry may include a current source and a diode-connected MOSFET that inhibit noise in the reference-voltage power supply from reaching the output nodes of the VGA or CTF. Although the present invention enables separate implementations of VGAs and CTFs, in one embodiment, a VGA function and a CTF function are implemented in a single set of (e.g., integrated) circuitry.

    Abstract: An AC coupling network has (a) a first pair of capacitances C1 connected between the input nodes and the output nodes and (b) a second pair of capacitances C2 cross-connected between the input nodes and the output nodes. The capacitances C1 and C2 are formed by sets of switched capacitors that can be configured to provide the network with different levels of attenuation while maintaining a constant AC coupling pole frequency. In particular, the sets of switched capacitors can be configured to ensure that C1+C2 remains constant, while C1−C2 varies. The present invention enables AC coupling to be implemented without using active devices such as operational amplifiers and/or buffers.

    Abstract: A variable-gain amplifier (VGA), with one or more amplifier stages, has two or more offset correction sources connected to apply offset correction signals at different locations in the VGA. In one embodiment, each amplifier stage has both an input offset correction source and an output offset correction source. In another embodiment, each amplifier stage of a multi-stage VGA has an input offset correction source. By sequentially calibrating each amplifier stage, starting with the initial stage and proceeding downstream, the entire VGA can be calibrated to achieve gain-independent compensation for the adverse affects of input and output voltage offsets at the input and output, respectively, of each stage.

    Abstract: Digital images that are produced by an image forming device may be processed using an edge enhancement technique to reduce the effects of halftone color depth reductions. For each element in the original image, certain detail elements are classified by examining the magnitude of pixel intensity gradients between elements of interest in a first window applied at each element and other elements in the first window. If a first predetermined condition is satisfied, those elements locations are stored. After halftoning, a morphological filter may be applied to the same element locations in the halftone image to enhance the halftone image.

    Abstract: A flow control including an annular flexible member and an internal post disposed downstream of the flexible member is described. The annular flexible member has a deflectable inner edge that defines a passage channel and the annular flexible member and internal post define a control gap therebetween wherein the deflectable inner edge of the annular flexible member deflects axially under increasing fluid pressure to reduce the control gap and consequently control fluid flow.
