High-precision miniaturized micromechanical accelerometers are used extensively in the
civilian and military fields. A novel self-test-on-chip method and time-multiplexing feedback …

This paper presents a high-resolution dual-integrating delta-sigma modulator (DI-DSM) for
low-power analog front-end (AFE) circuits in biomedical instrumentation. The AFE contains a …

This paper presents a wide linear output range biopotential amplifier for physiological
measurement frontend. The proposed amplifier consists of an open-loop rail-to-rail …

A sigma–delta-type digital converter (SDC) suitable for a resistive-potentiometer-type
displacement sensor with a floating slide is presented here. The delta modulator in a …

The experimental characterization through electrical, electromagnetic, and thermal
measurements of a new dc/dc converter architecture for high-voltage inputs, up to 60 V, is …

A fourth-order single-bit delta-sigma modulator is presented for sensor applications. The
loop filter is composed of both feedback and feedforward paths, and the modulator is …

Digital integrated circuits (ICs) can be integrated in low-cost digital CMOS technologies with
less number of masks than a mixed-signal CMOS technology. This property, however, limits …

This paper proposes a simple, yet accurate, analytical model forthe effect of opamp gain and
dynamics (slew rate and bandwidth) on the transfer function of switched-capacitor (SC) …

This work presents a macro modeling approach for the time‐mode cyclic ADC. The
proposed ADC macro model is realized using the time‐to‐voltage converter (TVC) and the …

Op-amps are crucial components in sigma–delta modulators (SDMs). As device dimensions
and supply voltages continue to scale down, it is increasingly critical to determine a suitable …
