Abstract :
Minimization of the switch noise level in switched-capacitor biquads is discussed. An analytical optimization procedure permits the designer to explore the different parameters in an expert way. A 20-kHz notch filter shows its feasibility. The signal-to-noise ratio is 90 dB and the chip area 1.0 mm/SUP 2/.
