VHDL-AMS Models for Current Conveyor Based Monolithic Operational Amplifiers

Pandiev Ivailo M.

International Journal of Microelectronics and Computer Science

2018

Vol. 9, nr 1

34--46

This paper focuses on analysis and behavioral modeling of second generation positive and negative current conveyors (CCII+s, CCII‒s), as well current-controlled current conveyors (CCCIIs). On the basis of the proposed CCII+ model improved behavioral models for three-terminal and four-termi-nal monolithic CFOAs are created. The models are developed by using VHDL analog and mixed-signal (VHDL-AMS) language and the descriptions are adapted to the SystemVision (version 5.5) simulation program, which is a part of the Mentor Graphics system. The proposed models simulate static and dynamic para-meters for differential and common-mode input signals at room temperature, including the parameters input offsets, accurate input impedances, non-dominant poles at differential input signals, AC common-mode rejection, PSRR effects, output impe-dances, slew rate limiting and terminal voltage/current operating ranges. The modeling parameters are extracted for commercially available four-terminal CFOA AD844A and CCCII OPA860 by analyzing semiconductor data books or through characterization measurements. For the validation process simulation and experi-mental results for sample electronic circuits are given.

Simple modeling approach for line impedance of on-chip CMOS interconnects

Ymeri H., Nauwelaers B., Maex K.

Journal of Technical Physics

2004

Vol. 45, no 1

71-77

Simple and accurate closed-form model enabling to calculate frequency-dependent distributed inductance and associated distributed series resistance per-unit-length of single on-chip interconnects on a lossy silicon substrate is presented. The closed-form formulas for the frequency-dependent series impedance parameters are obtained using a closed-form integration method and the vector magnetic potential equation. The proposed frequency-dependent inductance -L(omega) and resistance R(omega) per-unit-length formulas are shown to be in good agreement with the electromagnetic solutions.
