Analog circuit development system

Abstract

An analog circuit development system as a support in analog circuits design procedure is described. Analog circuit can be designed on a personal computer, uploaded to the board via a USB interface and immediately evaluated. The development board is based on Anadigm AN10E40 Field Programmable Analog Array (FPAA), which is controlled by a MC68HC908GP32 microcontroller, connected to the USB interface. The board features 4 analog inputs, 4 outputs and 5 selectable input/output lines. The whole system is powered from personal computer over USB 5V power lines by means of a DC-DC converter, so that it does not require any additional power supply. Analog circuit design is supported by Anadigm Designer software which also features time domain simulation and filter design tools.
