Reliable analysis of settling errors in SC integrators - application to high-speed low-power ΣΔ modulators design
(1999)
This paper presents a detailed study on the transient response of SC integrators taking into account the effects of amplifier finite gain-bandwidth product and slew-rate during, unlike previous models, both the integration ...

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 ...

Robust high-accuracy high-speed continuous-time CMOS current comparator
(Institution of Engineering and Technology, 1997)
The authors present a CMOS current comparator which employs nonlinear negative feedback to obtain high-accuracy (down to 1.5pA) and high-speed for low input currents (8ns at 50nA). The new structure features a speed ...

A mismatch-insensitive high-accuracy high-speed continuous-time current comparator in low voltage CMOS
(Institute of Electrical and Electronics Engineers, 1997)
This paper presents a CMOS current comparator which employs nonlinear feedback to obtain high-accuracy (down to 1.5 pA) and high-speed for low input currents (8 ns@50 nA). This structure is much faster for low currents ...

Non-ideal quantization noise shaping in switched-current bandpass ΣΔ modulators
(Institute of Electrical and Electronics Engineers, 1999)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the quantization noise shaping of SI BandPass SD Modulators (BPSDMs). Closed form equations are provided for the ...
