A Very Accurate Averaging Circuit Technique for the Switched Capacitor DAC
نویسندگان
چکیده
A simple and efficient method for improving the linearity of a two capacitor charge redistribution digital to analog converter (DAC) is presented. This method utilizes consecutive interchanging of the voltages on the capacitors for each bit being converted. It is shown that the accuracy achieved by the proposed algorithm is orders of magnitude higher compared to this of the conventional method. Simulations have been performed and have proved the feasibility of this new technique.

A Very Low Voltage 9th Order Linear Phase Baseband Switched Capacitor Filter (RESEARCH NOTE)
A very low voltage 9th order linear phase baseband switched capacitor (SC) filter has been designed to be used as part of a cellular GSM (Global System Mobile) receiver. A Gaussian-to-6dB filter of the order of seven is chosen and a second order function is added to reduce the group delay variations around. The filter uses a fully differential topology to increase the dynamic range and reduce t...

A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...

An oversampled digital-to-analog converter (DAC) with a 100-dB A-weighted dynamic range is presented. It uses a switched-capacitor (SC) array to transfer the sampled charges directly into the headphone driver. The overall DAC gain is precisely controlled by a novel reference stage. A new dynamic element matching algorithm, based on split-set data-weighted averaging (SDWA), is used to improve th...
متن کاملA triple-mode continuous-time sigma delta modulator with switched-capacitor feedback DAC for a GSM- EDGE/CDMA2000/UMTS Receiver
Time jitter in continuous-time modulators is a known limitation on the maximum achievable signal-to-noise-ratio (SNR). Analysis of time jitter in this type of converter shows that a switched-capacitor (SC) feedback digital-to-analog converter (DAC) reduces the sensitivity to time jitter significantly. In this paper, an and continuous-time fifth-order modulator with 1-bit quantizer and SC feedba...
