Simulate input offset Current for Current mirrors:
06/24/04 EDN Design Ideas / (added 1/05) Simulating the output-offset current of a current mirror is straightforward. You
simply have to apply an input current, measure the output current, and calculate the difference. This output-offset current, however, is not
equal to the input-offset current, especially when the circuit is not a 1-to-1 mirror.... |

SPICE simulates a fluorescent lamp : 11/06/97 EDN-Design
Ideas / (added 11/05) A hot-cathode fluorescent lamp (HCFL) contains a gaseous mixture that flows between two tungsten electrodes, or
filaments. In domestic applications, the mixture comprises mercury vapor and a small quantity of inert gas (krypton or argon). The inert gas
vaporizes the mercury during turn-on. To lengthen the filament's lifetime, a preheating period brings the electrodes to a high-enough
temperature before avalanche occurs. The warm-up is easy to effect by supplying the filaments with ac or dc during the first few hundred
milliseconds. During this emissive period, the filaments increase the electron population in the tube and consequently reduce the avalanche
potential, thereby resulting in a lower striking voltage for the lamp. Once struck, the lamp maintains a quasiconstant voltage, or "arc
voltage," across its.... |

Design Ideas / (added 1/05) PSpice, a member of the Spice family for PC users, is becoming a standard tool for analog and
mixed analog-digital simulation. Many analog designers are familiar with the software of Design Center, Design Lab, and OrCad (www.orcad.com)
PSpice and use the software in their everyday lives. This Design Idea should be helpful to those who design and simulate PLL systems at a
behavioral level.... |

Use PSPICE to model distributed gap cores: 03/17/05
EDN-Design Ideas / (added 5/05) PSpice software lets you create magnetic-core models that simulate nonlinear magnetic devices (Figure
1). These simulations are useful for observing hard-to-measure magnetic parameters such as core flux density, especially when you cannot
quickly procure a sample device. The required inputs to the PSpice magnetic-core model are initial permeability of the core material, data
points from the B-H magnetization curve, and the physical properties of the core, such as magnetic-path length, cross-sectional area, and
air-gap length.... |
