High-order lowpass and bandpass elliptic log-domain ladder filters
نویسندگان
چکیده
This paper reports a multitude of HSPICE simulation results corresponding to high-order (fifth, sixth and tenth) differential classA log-domain lowpass and bandpass ladder filter topologies. The designs are elliptically approximated and were obtained by means of an appropriately extended version of the XFILTER filter compiler. The non-desirable effect of the BJT finite beta is shown; circuit modifications mitigating to a certain extent the device nonideality-induced impact are also reported.

متن کاملHigh-fequency Cmos Integrated Filters for Computer Hard Disk Drive and Wireless Communication Systems
Operational transconductance amplifier and capacitor (OTA-C) filters have outstood among different types of filter due to high frequency and low power capabilities in the main stream digital CMOS technology. They have been widely used in computer hard disk drive (HDD) and wireless communication transceivers. OTA-C filters based on cascade and passive ladder simulation are well-known. However, m...

متن کاملHigh-Order Digital Parametric Equalizer Design
A family of digital parametric audio equalizers based on high-order Butterworth, Chebyshev, and elliptic analog prototype filters is derived that generalizes the conventional biquadratic designs and provides flatter passbands and sharper bandedges. The equalizer filter coefficients are computable in terms of the center frequency, peak gain, bandwidth, and bandwidth gain. We consider the issues ...
متن کاملQuantization noise analysis of wave digital and lossless digital integrator allpass/lattice filters
Quantization noise levels of two low-sensitive allpass filter structures, namely wave digital circulator filters (WDCF) and lossless digital integrator filters (LDIF), are compared. Allpass filters are of interest for design of lowpass and bandpass lattice filters. The results show, primarily, that second-order LDIFs have lower total quantization noise gains than corresponding WCDFs for any pol...
