Abstract :
An experimental 10.7-MHz switched-capacitor bandpass filter is demonstrated that exhibits a 400-kHz bandwidth with a 42-MHz sampling rate. Basic design issues of such high-frequency filters are also addressed with emphasis on dynamic range and power constraints. A theoretical square relation between power and center frequency agrees well with experimental results. The sixth-order differential bandpass filter chip occupies 2 mm2 using a 2.25-μm gate double-poly CMOS technology
