A low-noise bandgap voltage reference employing dynamic element matching
… that targets these issues through three dynamic element matching (DEM) subsystems. The first is a chopper OTA, and the second two are component rotation schemes: one to exchange the positions of two critical resistors, and the second to cycle through all BJTs, periodically selecting each …

Dynamic Element Matching Techniques For Delta-Sigma ADCs With Large Internal Quantizers
… dissipation, required area and complexity of the dynamic element matching (DEM) circuit required to attenuate digital-to-analog converter (DAC) mismatch errors. One way to overcome these drawbacks is to segment the feedback signal, creating a "coarse" signal and a "fine" signal. This reduces the …

An analysis of interconnection network effects of dynamic element matching digital-to-analog converters
… errors in the DAC's analog output signal. Dynamic Element Matching (DEM) is a method that can eliminate or reduce the effects of mismatch errors. In this thesis, DEM algorithms applied to a specific DEM DAC architecture that use several interconnection networks, including the Barrel …

A 4th order continuous-time [Delta] [Epsilon] ADC with VCO-based integrator and quantizer
… includes a scheme for performing fast dynamic element matching (DEM), enabling first-order shaping of unit-element mismatch in all feedback DAC's.

Construction of a random signal with a specific Psd and a uniform Pdf
The performance of a dynamic element matching (DEM) flash digital to analog converter (DAC) can be improved by controlling the DEM DAC's interconnection network with a random signal that has a specific power spectral density (PSD) and a uniform probability distribution function (PDF). Many …

Digital Harmonic-Cancelling Sinusoidal Signal Synthesis
… the 6 dB/bit rule. The third contribution is a dynamic element matching (DEM) technique to reduce the effect of mismatch while preserving the area and power cost efficiency of DHSSs. The theoretical proposals made in this thesis have been verified by implementing and testing two DHSS IC …
