The mixed-signal event-driven (MixED) method developed to simulate small portions of analog circuitry within a digital environment is demonstrated in a mixed signal application. The MixED models using concurrent iteration to account for analog nodes were coded and run in standard VHDL’93. Networks containing linear components such as sources, resistors, capacitors, inductors and operational amp...

The method of testing points generation for identification and correction of integral nonlinearity of high performance ADC is developed. The proposed method is based on averaging all voltages of multi-resistors voltage divider. The main idea of proposed method is in comparison results of analog to digital conversion obtained on different ranges of tested ADC for the same input signals. It is in...

For networks containing resistors, independent sources, gyrators, ideal transformers, diodes and other saturating monotone piecewise linear resistors, a new condition is proposed to guarantee uniqueness of solutions. This is both necessary and sufficient and is easy to test. It requires that the characteristics should satisfy a condition with the null vectors of the matrix of the linear part of...

High frequency measurements from 0.1 GHz to 40 GHz were performed on industry standard flip chip thin film resistors from Vishay Thin Film. The results of these measurements are reported in this paper. A lumped circuit model is presented that accurately predicts the response of various part values and case sizes. The results of the measurements and model are combined to demonstrate basic design...

 A novel analog divider is described in this paper. The circuit enables the division of a dc voltage with another dc voltage. The constant of the division is dependent upon a third dc voltage and a pair of resistors. Employing a precision source for the third dc voltage and matched resistors, an acceptable level of accuracy can be obtained. Keywords-sawtooth wave; integrator; comparator; analo...
