Abstract: Switched-capacitor charge pump implemented in FDSOI process technology and a method of forming them are provided. Embodiments include providing a FDSOI substrate; providing a plurality of stages of a first and a second pair of an NFET and PFET over the FDSOI substrate coupled between an input terminal and an output terminal, the first and second pair of each stage being opposite each other; providing a plurality of a first and a second capacitor over the FDSOI substrate, each first and second capacitor connected to a first and a second pair of NFET and PFET of a stage, respectively; connecting a back-gate of a NFET and a back-gate of a PFET of each pair; connecting the connected NFET and PFET back-gates to a front-gate of the pair; and connecting a source of each pair to a front gate of an opposite pair within the stage.

Abstract: Delta-sigma analog-to-digital converters (ADCs) and methods to calibrate methods to delta-sigma ADCs are disclosed. In one particular example, a delta-sigma ADC is described, including an n-bit feedback digital-to-analog converter (DAC) having a number of unit elements, and is configured to provide a feedback signal to a summing device, which generates a difference signal based on an analog input signal and the feedback signal. An n-bit ADC is included to generate an n-bit digital signal based on the difference signal. A dynamic element matching device selects one or more unit elements in the DAC based on the n-bit digital signal. A storage device, such as a memory, stores error coefficients corresponding to the plurality of unit elements. Finally, a digital corrector is included to receive the selection of unit elements, receive error coefficients corresponding to the selected unit elements, and adjust the n-bit digital signal based on the received error coefficients.

Abstract: A sigma delta signal treating apparatus includes: (a) a low pass filtered signal path including at least one low pass filter; and (b) a quantization noise filtered signal path coupled with the low pass filtered signal path; the quantization noise filtered signal path including at least one high pass filter and at least one feedback notch filter.
