A proposed third order noise shaping accelerometer interface circuit enhances the SNR compared with the previ ously presented interface circuits The solution for the two chip implementation is described and a novel cross coupled CDS integrator is proposed This scheme functions even with the large parasitic capacitances between the sensor and the interface circuit The op amp noise is rst order s...

Digital delta-sigma modulators (DDSMs) applied in fractional-N frequency synthesizers suffer from spurious tones which undermine the synthesizer’s spectral purity. We propose a solution featuring no hardware overhead while achieving equivalent spur elimination effect as using LFSR-dithering. This method can be implemented on MASH and single-loop DDSMs of 3rdand 2nd-order. key words: Digital del...

In this lab, we will cover a useful image processing technique called halftoning, which is the process of converting a gray scale image into a binary image. The process of halftoning is required in many present day electronic applications such as facsimile (FAX), electronic scanning and copying, and laser printing. This lab will cover the halftoning techniques known as ordered dithering and err...
