Measurements of switched capacitor filters generated with a silicon compiler

The use of silicon compilers for the generation of systems which contain analog subsystems is relatively novel; and the expected performance levels are not well known. A description is given of the actual performance obtained from switched-capacitor filter modules generated using the CONCORDE silicon compiler. An array of eight switch-capacitor biquadratic filters was fabricated utilizing a 3- mu m two-layer poly process and tested along with several filters from previous fabrication runs. Measurements of transfer function, noise floor, harmonic distortion, dynamic range, and temperature effects have been carried out.<
