Abstract:
A system and method are disclosed for providing an ultra low power scalable digital-to-analog converter architecture. Refresh buffer circuits are provided to buffer a voltage reference resistor string. The refresh buffer circuits may be coupled to the resistor string at selected binary fold points. The refresh buffer circuits can reduce the output impedance of the resistor string. Also, each digital-to-analog converter channel can be provided with a multi-dimensional multiplexer that minimizes settling time. The number of refresh buffer circuits and the number of dimensions of the multiplexer can be selected to maximize circuit performance for a given load capacitance and bit rate of the digital-to-analog converter.
Abstract:
A method for controlling residual stress in a structure in a MEMS device and a structure thereof includes selecting a total thickness and an overall equivalent stress for the structure. A thickness for each of at least one set of alternating first and second layers is determined to control an internal stress with respect to a neutral axis for each of the at least alternating first and second layers and to form the structure based on the selected total thickness and the selected overall equivalent stress. Each of the at least alternating first and second layers is deposited to the determined thickness for each of the at least alternating first and second layers to form the structure.
