A CMOS 0.8 μm fully differential current mode buffer for HF SI circuits
(Elsevier, 1998)
We present a high-frequency fully-differential current-mode buffer to interface off-chip currents with no significant degradation of the frequency response, and to measure current-mode ICs using standard equipment. It has ...

Harmonic Distortion in Fully-Differential Switched-Current Sigma-Delta Modulators
(1999)
This paper presents a systematic analysis of the harmonic distortion in SD modulators (SDMs) implemented with fully-differential switched-current (SI) circuits. Closed form expressions are derived for the third-order ...

A CMOS fully-differential bandpass ΣΔ modulator using switched-current circuits
(Institute of Electrical and Electronics Engineers, 1995)
This paper presents a fourth-order bandpass sigma-delta modulator that has been designed using fully-differential switched-current circuits in a 0.8μm CMOS technology. The modulator prototype has been obtained by applying ...

Using CAD tools for shortening the design cycle of high-performance sigma–delta modulators: A 16·4 bit, 9·6 kHz, 1·71 mW ΣΔM in CMOS 0·7 μm technology
(Wiley-Blackwell, 1997)
This paper uses a CAD methodology proposed by the authors to design a low-power 2nd-order Sigma-Delta Modulator (ΣΔM). This modulator has been fabricated in a 0.7μm CMOS technology to be used as the front-end of an ...

A fourth-order bandpass ΣΔ modulator using current-mode analog/digital circuits
(Institute of Electrical and Electronics Engineers, 1996)
We present a fourth-order bandpass ΣΔ switched-current modulator IC in 0.8 μm CMOS single-poly technology. Its architecture is obtained by applying a lowpass to bandpass transformation (z-1 →-z-2) to a second-order lowpass ...

A Tool for automated design of sigma-delta modulators using statistical optimization
(Institute of Electrical and Electronics Engineers, 1993)
A tool is presented which starting from high level specifications of SC σδ modulators (resolution, bandwidth and oversampling ratio) calculates first optimum specifications for the building blocks (op-amps, comparator, ...

Tools for Automated Design of ΣΔ Modulators
(Springer, 1997)
We present a set of CAD tools to design ΣΔ modulators. They use statistical optimization to calculate optimum specifications for the building blocks used in the modulators, and optimum sizes for the components in these ...

A 2.5MHz 55dB Switched-Current BandPass ΣΔ Modulator for AM Signal Conversion
(Institute of Electrical and Electronics Engineers, 1997)
We present a Switched-Current (SI) fourth-order bandpass ΣΔ modulator IC prototype. It uses fully-differential circuits in 0.8μm CMOS technology to obtain a Dynamic Range (DR) larger than 55dB at 2.5MHz center frequency ...

Behavioral modeling of PWL analog circuits using symbolic analysis
(Institute of Electrical and Electronics Engineers, 1998)
Behavioral models are used both for top-down design and for bottom-up verification. During top-down design, models are created that reflect the nominal behavior of the different analog functions, as well as the constraints ...
