Analog circuit design can be greatly increased if aided with some design tools and simulators. Of course there is notling like swaping components and scribbling on paper, but if you have designed one too many filters or amplifiers, these tools should help you increase your productivity and take out some of the monotony.
This is an Analog Circuit simulator of high quality. It has a decent component library and is well documented and even has a tutorial. More information is available at the Circuit Theory Laboratory Website.
Binaries are available for the following platforms:Dec Alpha
HP 700
Linux
Solaris
Sparc (Sun 4)
Windows 3.1Current online documentaion is also available.

Adore is a technology-independent module generator for Switched-Capacitor (SC) filters. The layouts it generates for SC circuits include ratioed capacitors, double-throw switches, and operational amplifiers (op-amps). Capacitors are generated by the program itself. They have two terminals corresponding respectively to the top- and bottom-plate of the capacitor. This simulator can be compiled on both the VAX and the Unix operating systems.
