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 ...

Algorithm for efficient symbolic analysis of large analogue circuits
(Institution of Engineering and Technology, 1994)
An algorithm is presented that generates simplified symbolic expressions for the small-signal characteristics of large analogue circuits. The expressions are approximated while they are computed, so that only the most ...

Offset-calibration with Time-Domain Comparators Using Inversion-mode Varactors
(Institute of Electrical and Electronics Engineers, 2019)
This paper presents a differential time-domain comparator formed by two voltage controlled delay lines, one per input terminal, and a binary phase detector for comparison solving. The propagation delay through the respective ...

A CMOS analog adaptive BAM with on-chip learning and weight refreshing
(Institute of Electrical and Electronics Engineers, 1993)
In this paper we will extend the transconductance-mode (T-mode) approach [1] to implement analog continuous-time neural network hardware systems to include on-chip Hebbian learning and on-chip analog weight storage capability. ...

Fourth-order cascade SC ΣΔ modulators: a comparative study
(Institute of Electrical and Electronics Engineers, 1998)
Fourth-order cascade ΣΔ modulators are very well suited for IC implementation using analog sampled-data circuits because of their robust, stable operation and their capability to achieve high resolution and wide bandwidth ...

Analysis of error mechanisms in switched-current Sigma-Delta modulators
(Springer, 2004)
This paper presents a systematic analysis of the major switched-current (SI) errors and their influence on the performance degradation of ΣΔ Modulators (ΣΔMs). The study is presented in a hierarchical systematic way. First, ...
