This paper describes a low-power 22-bit incremental ADC, including an on-chip digital filter and a low-noise/low-drift oscillator, realized in a 0.6-mum CMOS process. It incorporates a novel offset-cancellation scheme based on fractal sequences, a novel high-accuracy gain control circuit, and...
Complete design is simulated on 180 nm UMC CMOS technology with power supply voltage is 1.2V. Simulation results are obtained as: signal-to-noise ratio (SNR) is 55.94dB, effective number of bits (ENOB) is 11.14, dynamic range is 68.83dB and average power consumed by the ADC in one cycle...
A 15-bit low-power incremental ADC is designed for sensor applications. The ADC is designed to be frequency-scalable by 1000 times from 1.67S/s to 1.67kS/s. To reduce power, an opamp with class AB characteristics is used. The design was fabricated in 0.18/Ltm CMOS and occupies an area...
A 20-bit incremental ADC for battery-powered sensor applications is presented. It is based on an energy-efficient zoom ADC architecture, which employs a coarse 6-bit SAR conversion followed by a fine 15-bit ΔΣ conversion. To further improve its energy efficiency, the ADC employs integrators ...
摘要: With a 55-MHz clock, the measured dynamic range and the SFDR are 100 dB and 110 dB, respectively, at a conversion rate of 1.25 MS/s. The power consumption is 27.7 mW from a 3-V power supply. This gives a Schreier FoM of 173.6 dB....
