Conversor DSB-SSB a capacitores chaveados por transformador de Hilbert em tecnologia CMOS de 180 nm
… presented. Implemented by discrete-time switched-capacitor circuits, it adopts an Infinite Impulse Response (IIR) filter to realize a Hilbert transformer as alternative to digital implementations which take advantage of high processing capacity from parallel digital circuits to obtain the Hilbert …

Low-power high-performance SAR ADC with redundancy and digital background calibration
… the key linearity and speed limiting factors are capacitor mismatch and incomplete digital-to-analog converter (DAC)/reference voltage settling. In this the- sis, a sub-radix-2 SAR ADC is presented with several new contributions. The main contributions include investigation of using digital error …

Digital calibration of nonlinear memory errors in sigma-delta ADCs
… treating both amplifier distortion and capacitor mismatch in one frame. The design perspectives of low gain two-stage amplifiers are studied with other practical design issues in the implementation. The ADC employing 29 dB gain amplifiers achieves 85 dBc spurious-free dynamic range and …

ANALYSIS, OPTIMIZATION, AND PRACTICAL DESIGN OF A SPLIT-PHASE DICKSON SWITCHED CAPACITOR CONVERTER FOR HIGH CURRENT APPLICATIONS
The Switched-Capacitor Converter (SCC) topology has been gaining attention from researchers because of their advantages of higher power density, better switch utilization, and low component stress. However, SCCs have a fundamental downside in which capacitor charge redistribution causes significant …

Low-power high-performance SAR ADC design with digital calibration techniques
… effectively and efficiently remove the static mismatch errors in the analog-to-digital (A/D) conversion. They enable aggressive scaling of the capacitive digital-to-analog converter (DAC), which also serves as sampling capacitor, to the kT/C limit. As a result, outstanding conversion linearity, …
