The open-circuit time constant (OCT) method is an approximate analysis technique used in electronic circuit design to determine the corner frequency of complex circuits. It is a special case of zero-value time constant (ZVT) method technique when reactive elements consist of only capacitors.
Setting a capacitor value to zero corresponds to an open circuit, while a zero-valued inductor is a short circuit. So for calculation of the , all other capacitors are open-circuited and all other inductors are short-circuited. This is the essence of the ZVT method, which reduces to OCT when only capacitors are involved.
Micro-Cap [1] is a SPICE compatible analog/digital circuit simulator with an integrated schematic editor that provides an interactive sketch and simulate environment for electronics engineers. It was developed by Spectrum Software , and was only available with a paid commercial license. [ 2 ]
The signal delay of a wire or other circuit, measured as group delay or phase delay or the effective propagation delay of a digital transition, may be dominated by resistive-capacitive effects, depending on the distance and other parameters, or may alternatively be dominated by inductive, wave, and speed of light effects in other realms.
Capacitance is the ratio of the change in an electric charge in a system to the corresponding change in its electric potential. The capacitance is a function only of the geometry of the design (e.g. area of the plates and the distance between them) and the permittivity of the dielectric material between the plates of the capacitor. For many ...
Small-signal modeling is a common analysis technique in electronics engineering used to approximate the behavior of electronic circuits containing nonlinear devices with linear equations. It is applicable to electronic circuits in which the AC signals (i.e., the time-varying currents and voltages in the circuit) are small relative to the DC ...
The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
The compensation capacitance C is chosen such that f d < f 1. Hence, the frequency response of a dominant pole compensated open loop Op-Amp circuit shows uniform gain roll off from f d and becomes 0 at f 1 as shown in the graph. Frequency response in Dominant Pole compensation. The advantages of dominant pole compensation are: 1. It is simple ...
