Abstract: A new circuit simulator is described which combines the gate-to-gate signal propagation technique used in logic simulators with detailed device representation and circuit analysis at the gate level. MOTIS is specialized for analyses of MOS logic circuits during the prelayout and postlayout phases of a design. The device modeling takes account of the back-gate bias effects and the bidirectionality of transmission gates. The simulation mechanism and the detailed device modeling lead to simulation of the dependence of propagation delays on input waveforms. The loading and device capacitances are assumed to be constant and bootstrapping effects are not simulated. The simulator has been implemented on a minicomputer having a 32K-word memory of 16-bit words, a disk module, and a storage CRT/keyboard terminal. This configuration allows simulation of circuits having 1000 gates with an operational speed of approximately 2 ms of real time per gate per nanosecond of circuit time.

TL;DR: In this article, the use of a variety of inexpensive integrated circuits, students in a one−quarter introductory electronics course are able to design a large number of different types of useful circuits.
Abstract: Through the use of a variety of inexpensive integrated circuits, students in a one−quarter introductory electronics course are able to design a large number of different types of useful circuits. Students design from very simple models of circuit behavior with complications treated as perturbations. The general approach is described and then its use is shown in a number of analog and digital applications.

TL;DR: In this paper, the authors used three independent noise generators to simulate the preamplifier output of a thin cylindrical detector and found that the resulting simulator can be used to obtain the value of beta, a coupling coefficient from which the absolute sensitivity to gravitational pulses can be obtained.
Abstract: The equivalent circuit of a thin cylindrical detector is a short-circuited delay line as evidenced by the quantitative agreement between test pulse response of actual detector units and of an electronic simulator. The main section of the simulator reproduces pure detector signals (including thermal noise) as seen by an ideal preamplifier. The complete instrument simulates actual preamplifier output using a total of three independent noise generators. Electrical tests on actual detectors yielded to the value of beta , a coupling coefficient from which the absolute sensitivity to gravitational pulses can be obtained.
