Abstract: A DAC architecture is described. The architecture is specifically adapted to provided an analog voltage output based on a digital input word. The architecture includes a resistor ladder configuration sub-divisible into a first component, adapted to convert a lower part of the input word, and a second component adapted to convert an upper part of the input word. The DAC is calibrated such that the first component can be used to tune the output of the second component on selection of specific segment from the second component.

Abstract: An architecture of an integrated circuit allows for the canceling of noise sampled on a capacitor in the integrated circuit, after an input signal has already been sampled. Thermal noise correlated with an arbitrary input signal may be canceled after selectively controlling a plurality of switching devices during a sequence of clock phases. An auxiliary capacitor may be used to store a voltage equal to the thermal noise and enable the cancellation of the thermal noise from the sampled signal in conjunction with a noise cancellation unit.

Abstract: Techniques to provide calibration of a measurement system in conjunction with measurement operations. The techniques may include providing a reference device in a signal processing chain within the measurement system. An excitation signal may be driven through the reference device while it may be connected to the signal processing chain within the measurement system and a calibration response may be captured. During a measurement operation, the reference device connection may be complemented with a sensor connection in the signal processing chain and the excitation signal may be driven through the signal processing chain. A measurement response may be captured from the system. The measurement system may generate a calibrated measurement signal that accounts for phase and/or amplitude errors within the system from the calibration response and the measurement response.

Abstract: Embodiments of the present invention provide a drive signal for a motor-driven mechanical system whose frequency distribution has zero (or near zero) energy at the expected resonant frequency of the mechanical system. The drive signal may be provided as a pair of steps sufficient to activate movement of the mechanical system and then park the mechanical system at a destination position. The steps are spaced in time so as to have substantially zero energy at an expected resonant frequency fR of the mechanical system. The drive signal may be filtered to broaden a zero-energy notch at the expected resonant frequency fR.

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.
