Micro Power High-Resolution A/D Converter

چکیده
Due to their low number of biased components, algorithmic A/D converters are often used in low power implementations. This paper describes an algorithm developed at the Institute of Microtechnology (IMT) which allows extending performances of cyclic RSD converters, without greatly impairing its benefits (reduced silicon area, low consumption). To achieve a Total Harmonic Distortion + Noise (THD+N) of 14 bits as well as a Dynamic Range (DR) of 16 bits, this algorithm combines oversampling, filtering, preand postprocessing. Results of such converter are discussed and widely presented.

متن کاملUltra-low-power multiplexed electronic driver for high resolution deformable mirror systems
We present a new multiplexed high-voltage driver architecture that departs from previous MEMS deformable-mirror drivers. Just one D/A converter and one high-voltage amplifier module drive the entire actuator array through a rowcolumn addressing scheme. This approach reduces operational power consumption of a multiple-channel deformablemirror driver by two orders of magnitude. It can provide for...
