Application of programmable analog device in signal process

This paper has introduced the internal structural principle of ispPAC10 that lattice semiconductor company puts it to the market and it´s application in signal process, detailedly elaborated the flexible and changeable function in amplification, filtering, attenuation, and have discussed the design method of each kind of function. This paper have given the design thought, configuration method and emulation waveform of ordinary gain, grade gain, integer ratio gain amplifier (or attenuation) and biguad filter that designed with the platform PAC-Designer.
