dc.description.abstract A micropower-compatible time-multiplexed sc speech spectrum analyzer embodying several new design methodologies is described. In the bandpass filter (BPF) section, the dc offset differences between channels are reduced by a careful biquadratic filter design, and a capacitor sharing technique is employed to reduce chip area. A new time-multiplexed fullwave rectifier (FWR) is also proposed. Expressions for the errors that limit the accuracy of the running spectrum due to nonidealities are formulated. An experimental four-channel spectrum analyzer has been fabricated and measurements from prototypes showed that the proposed design methodologies are satisfactory in achieving the design specifications.
