| Summary: | Switched-capacitor techniques are applied to the design of a bandpass filter circuit
satisfying the specification for filters used in acoustical measurement. Dependence of
the switched-capacitor filter characteristics on its clock frequency allows the
achievement of the whole range of preferred midband frequencies from 10 Hz to 20
kHz by a single circuit. The design produces a circuit which is insensitive to parasitic
capacitances and element-value variations. This offers the possibility for the filter and
all its accessories to be fully integrated using MOS technology |
