Embodiment Construction

[0021] The present subject matter provides a method, apparatus and system for switched capacitor array control that can address the transient and lifetime issues noted above with respect to conventional binary control schemes. In one aspect, the present subject matter provides a method for operating an array 100 of binary elements 10 that can be independently enabled or disabled. For example, as discussed above, each binary element 10 may comprise a capacitor, and each element may have its own independently controllable driver.

[0022] For such an array 100, inputs corresponding to desired behavior may be provided. Despite the problems associated with conventional control schemes as discussed above, binary control inputs can advantageously limit the number of bits in control communications and registers. However, to avoid this massive switching of conventional binary control algorithms, instead of a fixed assignment of elements into binary subsets, the binary control words c...

Abstract

The present subject matter relates to methods, devices, and systems for switched array control. For an array of two-state elements that can be independently positioned in either an active state or an inactive state, the methods, devices, and systems can determine a linear number D of elements in the active state needed to achieve a total combined activity corresponding to a desired behavior, compare a number A of elements in an active state to the linear number D of elements needed to achieve the desired behavior, activate a first number n of inactive elements, and deactivate a second number m of active elements, wherein the difference between the first number n and the second number m is equal to the difference between the linear number D of elements needed to achieve the desired behavior and the present number A of elements in an active state.

Description

[0001] priority claim [0002] This application claims the benefit of US Provisional Patent Application Serial No. 61 / 671,494, filed July 13, 2012, the entire disclosure of which is hereby incorporated by reference. technical field [0003] The subject matter disclosed herein generally relates to methods, devices, and systems for operating an array of binary elements that can be independently activated or inactive. More specifically, the subject matter disclosed herein relates to systems and methods for switched capacitor array control. Background technique [0004] Arrays of identical or structurally substantially similar switched capacitor elements can be electrically combined into groups (eg, via interconnections) to provide a given amount of collective capacitance. In previous implementations of such arrays, subgroups have been grouped and driven by a single control line to minimize the amount of drive circuitry required. Such a configuration enables the use of mixed l...
