An efficient approach to model distortion in weakly nonlinear Gm - C filters

Abstract

Standard wireless communication circuits extensively use bandpass Gm-C filters, whose total harmonic distortion (THD) and intermodulation distortion (IMD) have been estimated and modeled previously. However previous approaches have considered only third order nonlinearity effects assuming fully balanced OTAs. This assumption does not hold good for practical… (More)
