    CPC classification number: H02P25/034

    Abstract: Embodiments of the present invention provide a motor-driven mechanical system with a detection system to measure properties of a back channel and derive oscillatory characteristics of the mechanical system. Uses of the detection system may include calculating the resonant frequency of the mechanical system and a threshold drive DTH required to move the mechanical system from the starting mechanical stop position. System manufacturers often do not know the resonant frequency and DTH of their mechanical systems precisely. Therefore, the calculation of the specific mechanical system's resonant frequency and DTH rather than depending on the manufacturer's expected values improves precision in the mechanical system use. The backchannel calculations may be used either to replace or to improve corresponding pre-programmed values.

    Abstract: A no-missing-code output from a SAR, pipeline, folding, flash analog to digital conversion can be obtained by providing an analog input to an analog to digital converter having a predetermined m bit resolution output and a predetermined missing code capability and generating in a digital filter from the m bit output and the dither of the random noise components of the m_bit output n bit output and greater than the predetermined missing code capability of the analog to digital converter.

    Abstract translation: 本发明的实施例提供一种具有检测系统的电机驱动机械系统，用于测量后通道的性质并导出机械系统的振荡特性。 检测系统的使用可以包括计算机械系统的谐振频率和将机械系统从起动机械停止位置移动所需的阈值驱动DTH。 系统制造商往往不了解其机械系统的谐振频率和DTH。 因此，特定机械系统的谐振频率和DTH的计算而不是依赖于制造商的预期值来提高机械系统使用的精度。 反向通道计算可用于替换或改善相应的预编程值。

    Abstract: A charge pump system for a fast locking phase lock loop includes a set n of charge pump units; and a control logic circuit for enabling the set of n charge pump units to produce up and down charge pulses with a nominal charge pump mismatch in a wide bandwidth mode; and in a narrow bandwidth mode enabling at least a subset of the n charge pump units sequentially to produce an average charge pump mismatch in narrow bandwidth mode that matches the nominal charge pump mismatch in the wide bandwidth mode.
