Conference Paper: Theoretical and practical minimum of the power Consumption of 3 ADCs in SC technique
[Show abstract] [Hide abstract]
ABSTRACT: In this paper the theoretical and practical minimum of the power consumption is investigated for 3 ADC architectures, which are predestined for low conversion speed and applications in lowpower sensor readout circuits. The analysis is made for the switched capacitor versions of the SAR ADC, cyclic ADC and sigmadelta modulator. The theoretical limit of the power efficiency is investigated by a commonly used figure of merit (FOM). As a case study two lowpower ADCs were designed and fabricated. In order to compare ADCs fabricated in different technologies a technologyindependent FOM is introduced.Circuit Theory and Design, 2007. ECCTD 2007. 18th European Conference on; 09/2007 
Conference Paper: A 0.026mm2 capacitancetodigital converter for biotelemetry applications using a charge redistribution technique
[Show abstract] [Hide abstract]
ABSTRACT: This paper proposes a direct capacitancetodigital converter (CDC) for biotelemetry applications. The proposed circuit is based on a charge redistribution technique using a capacitive sensor and a ranging capacitor array. The circuit does not require accurate reference voltages, so it is robust for fluctuation of supply voltage. Outputcode range can be dynamically zoomed in arbitrary capacitance range of sensor output by using the ranging capacitor array. An 8bit converter with an active area of 0.026 mm<sup>2</sup>, consuming 0.9 nJ per sample, is demonstrated. The proposed circuit maintains its performance even in the condition of 28% fluctuations in supply voltage. Measurement results of the readout circuit are also demonstrated, which shows that the proposed circuit can work well in the presence of large parasitic capacitances.SolidState Circuits Conference, 2007.
