software to design amplifier

[h.galeh]

I want to design an audio amplifier(preamp and power) . is there any software. a software that can design amplifier?
please introduce me the best of them.
thank so much previously

I don't think there are specific simulators for amplifier design , you can use any of the LTspice, multisim, orcad etc

I know that orcad is a simulating environment but , how should I design?
please introduce me ltspice and multisim

 

[alexan_e]

LTspice is a free full version simulator from Linear Technology Linear Technology - Design Simulation and Device Models
Multisim now belongs to National Instruments , this is a commercial software

You can find tutorials in both sites

When you say how to design I don't know what exactly you mean.
I assume you have worked with simulator software, basically you connect all the components to make a schematic (resistors, transistors, mosfets , power supply etc) and then you can simulate the design to measure different parameters like frequency response, phase, gain, noise etc

I mean, I dont know resistor values and also I dont know what transistor model I shold use

Unfortunately software doesn't design things. People design things. Simulators allow you to see how well a design might work prior to building it. It allows you to experiment and optimize the design quickly. So, first you need to learn some basics. "The Art of Electronics" by Horowitz & Hill, while a little old, is still probably a good starting point.
