IDAC: an interactive design tool for analog CMOS circuits

A design system has been developed which is able to design transconductance amplifiers, operational amplifiers, low-noise BIMOS amplifiers, voltage and current references, quartz oscillators, comparators, and oversampled A/D converters including their digital decimation filter starting from building-block and technology specifications. This design system, called Interactive Design for Analog Circuits (IDAC), is able to size a library of analog schematics (actually more than 40) as a function of technology (p-well and n-well CMOS) and desired building-block specifications. IDAC also generates a complete data sheet, an input file for SPICE2, and an input file for the analog layout program ILAC.
